Patent documents 1 and 2 describe “a step of creating a correspondence table representing a relationship between X-ray analysis data and the cumulative fatigue degree” (claim 1). Patent document 3 describes “a procedure for performing a deterioration acceleration test on a test body on which a coating film to be diagnosed is formed under predetermined conditions” (claim 1).

For an electrolytic apparatus including an ion exchange membrane or the like, production efficiency of a product produced by the electrolytic apparatus easily decreases when performance of the ion exchange membrane or the like degrades. Accordingly, it is preferable to promptly recover the performance of the ion exchange membrane or the like. In order to promptly recover the performance of the ion exchange membrane or the like, it is preferable to promptly identify a factor for the degradation of the performance of the ion exchange membrane or the like and to promptly take countermeasures to recover the performance.
To take countermeasures against the degradation of the performance of the ion exchange membrane or the like, by benchmarking against past degradation of the performance, positioning of the degradation of the performance in a benchmark object can be preferably recognized as compared with the past degradation of the performance. With this configuration, it becomes easier to decide content of performance recovery measures of the ion exchange membrane or the like and a time to implement the recover measures. In addition, for this benchmark, it is preferable to use as much data of the past degradation of the performance as possible.
When the degradation of the performance occurs in the ion exchange membrane or the like, it is preferably possible to recognize a period of time from a timing at which the degradation of the performance is recognized to an end of life of the ion exchange membrane or the like. With this configuration, it becomes easier to decide a timing at which the ion exchange membrane or the like is to be regenerated. In addition, when the ion exchange membrane or the like is to be replaced, it becomes easier to decide a time when the ion exchange membrane or the like is prepared.

The electrolyte solution is, for example, an NaCl (sodium chloride) aqueous solution. The electrolyzer 90 generates Cl2 (chlorine), NaOH (sodium hydroxide), and H2 (hydrogen) through electrolysis of an NaCl (sodium chloride) aqueous solution, for example. The electrolyzer 90 may include a plurality of electrolytic cells 91 (electrolytic cell 91-1 to the electrolytic cell 91-N, where N is an integer greater than or equal to 2). N is, for example, 50.
In the present example, the input tube 92 and the input tube 93 are connected to each of the electrolytic cell 91-1 to the electrolytic cell 91-N. Liquid 70 is inputted into each of the electrolytic cell 91-1 to the electrolytic cell 91-N. The liquid 70 may be inputted into each of the electrolytic cell 91-1 to the electrolytic cell 91-N after passing through the input tube 92. The liquid 70 is an aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide. The alkali metal is an element belonging to group 1 of the periodic table of the elements. When the liquid 70 is an aqueous solution of an alkali metal chloride, the liquid 70 is an aqueous solution of NaCl (sodium chloride), for example. When the liquid 70 is an aqueous solution of an alkali metal hydroxide, the liquid 70 is a KOH (potassium hydroxide) aqueous solution or an NaOH (sodium hydroxide) aqueous solution, for example.
Liquid 72 is inputted into each of the electrolytic cell 91-1 to the electrolytic cell 91-N. The liquid 72 may be inputted into each of the electrolytic cell 91-1 to the electrolytic cell 91-N after passing through the input tube 93. The liquid 72 is an aqueous solution of an alkali metal hydroxide. The liquid 72 is, for example, an NaOH sodium hydroxide aqueous solution. When the liquid 70 is an aqueous solution of an alkali metal hydroxide, the liquid 72 is an aqueous solution of a same alkali metal hydroxide (for example, KOH).
In the present example, the output tube 94 and the output tube 95 are connected to each of the electrolytic cell 91-1 to the electrolytic cell 91-N. Liquid 76 and gas 78 (described below) are outputted from each of the electrolytic cell 91-1 to the electrolytic cell 91-N. The liquid 76 and the gas 78 (described below) may be outputted to the outside of the electrolytic apparatus 200 after passing through the output tube 95. The liquid 76 is an aqueous solution of an alkali metal hydroxide. When the liquid 72 is an NaOH (sodium hydroxide) aqueous solution, the liquid 76 is an NaOH (sodium hydroxide) aqueous solution. The gas 78 (described below) may be H2 (hydrogen).
Liquid 74 and gas 77 (described below) are outputted from each of the electrolytic cell 91-1 to the electrolytic cell 91-N. The liquid 74 and the gas 77 (described below) may be outputted to the outside of the electrolytic apparatus 200 after passing through the output tube 94. The liquid 74 is an aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide. When the liquid 70 is an NaCl (sodium chloride) aqueous solution, the liquid 74 is an NaCl (sodium chloride) aqueous solution. When the liquid 70 is a KOH (potassium hydroxide) aqueous solution, the liquid 74 is a KOH (potassium hydroxide) aqueous solution. When the liquid 70 is an NaCl (sodium chloride) aqueous solution, the gas 77 (described below) is Cl2 (chlorine). When the liquid 74 is a KOH aqueous solution (potassium hydroxide), the gas 77 (described below) is O2 (oxygen).
The input tube 92 and the output tube 94 are connected to the anode chamber 79. The input tube 93 and the output tube 95 are connected to the cathode chamber 98. The liquid 70 is inputted into the anode chamber 79. The liquid 72 is inputted into the cathode chamber 98.
The ion exchange membrane 84 is a membranous substance that prevents passage of ions having a same sign as the ions arranged in the ion exchange membrane 84 and allows passage of only ions having different signs. In the present example, the ion exchange membrane 84 is a membrane that allows passage of Na+ (sodium ions) and prevents passage of Cl− (chloride ions).
The anode 80 and the cathode 82 may be maintained at a predetermined positive potential and a predetermined negative potential, respectively. The liquid 70 inputted into the anode chamber 79 and the liquid 72 inputted into the cathode chamber 98 are electrolyzed by a potential difference between the anode 80 and the cathode 82. In the anode 80, the following chemical reaction occurs.
2 Cl−→Cl2+2e− Chemical Formula 1
When the liquid 70 is an NaCl (sodium chloride) aqueous solution, NaCl (sodium chloride) is ionized into Na+ (sodium ion) and Cl− (chloride ion). Cl2 (chlorine) gas is generated in the anode 80 by the chemical reaction shown in Chemical Formula 1. The gas 77 (the Cl2 (chlorine) gas) and the liquid 74 may be outputted from the anode chamber 79. Na+ (sodium ion) moves from the anode chamber 79 to the cathode chamber 98 via the ion exchange membrane 84 by an attractive force from the cathode 82.
In the anode chamber 79, liquid 73 may be retained. The liquid 73 is an aqueous solution of an alkali metal chloride or an aqueous solution of an alkali metal hydroxide. In the present example, the liquid 73 is an NaCl (sodium chloride) aqueous solution. The Na+ (sodium ion) concentration and the Cl− (chloride ion) concentration of the liquid 73 may be less than the Na+ (sodium ion) concentration and the Cl− (chloride ion) concentration of the liquid 70.
In the cathode 82, the following chemical reaction occurs.
2H2O+2e−→H2+2OH− Chemical Formula 2
When the liquid 72 is an NaOH (sodium hydroxide) aqueous solution, NaOH (sodium hydroxide) is ionized into the Na+ (sodium ions) and OH− (hydroxide ions). H2 (hydrogen) gas and OH− (hydroxide ions) are generated in the cathode 82 by the chemical reaction shown in Chemical Formula 2. The gas 78 (the H2 (hydrogen) gas) and the liquid 76 may be outputted from the cathode chamber 98.
In the cathode chamber 98, liquid 75 may be retained. The liquid 75 is an aqueous solution of an alkali metal hydroxide. In the present example, the liquid 75 is an NaOH (sodium hydroxide) aqueous solution. In the present example, the liquid 75 in which OH− (hydroxide ions) generated by the chemical reaction shown in Chemical Formula 2 and Na+ (sodium ions) moved from the anode chamber 79 are dissolved is retained in the cathode chamber 98.
The analysis system 100 may include an information terminal 30. The information terminal 30 may have a display unit 32. The information terminal 30 may be a stationary computer terminal, or may be a tablet computer. When the information terminal 30 is a tablet computer, the display unit 32 may be a monitor of the tablet computer.
The information terminal 30 and the terminal device 10 may communicate through a wire 99, or may communicate by way of short range radio such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). The wire 99 is, for example, a USB cable or the like. In the present example, the information terminal 30 has a first transmission unit 14.
The electrolyzer 90 and the server 20 may be arranged in different locations. The different locations may refer to different geographical locations. The server 20 is installed, for example, in City A in Japan. When the server 20 is installed in City A in Japan, the electrolyzer 90 may be installed in City B in Japan which is different from City A, or may be installed in a foreign country other than Japan. A location in which the server 20 is arranged is set as a location Sa. A location in which the electrolyzer 90 is arranged is set as a location Sb.
The electrolyzer 90 may be arranged in a same location as the terminal device 10 and the information terminal 30. The same location may refer to a same geographical location. The terminal device 10 and the information terminal 30 may be arranged in the location Sb. When the electrolyzer 90 is installed in a predetermined plant, the electrolyzer 90 and also the terminal device 10 and the information terminal 30 may be used by a same user in the predetermined plant.
The element acquisition unit 12 acquires an amount of an element contained in an object 110 in the electrolyzer 90 (see
The object 110 may be the ion exchange membrane 84 (see
The element acquisition unit 12 may further acquire a type of the element contained in the object 110. When the object 110 is irradiated with the X-rays 112, energy of the X-rays 114 emitted from the object 110 depends on the type of the element. Thus, when the terminal device 10 is the portable X-ray fluorescence analysis terminal device, the element acquisition unit 12 can acquire the type of the element by measuring the energy of the emitted X-rays 114.
The liquid 70 (see
Since the electrolyzer 90 electrolyzes the liquid 70, in accordance with duty time of the electrolyzer 90, an element inputted in the predetermined treatment on saltwater may be accumulated in the ion exchange membrane 84 (see
The anode 80 and the cathode 82 are in contact with the liquid 73 and the liquid 75, respectively. The liquid 73 and the liquid 75 are electrolyte solutions. Surfaces of the anode 80 and the cathode 82 may be coated with Ru (ruthenium) or the like to suppress a rise of a voltage of the electrolyzer 90. When the coating on the surfaces of the anode 80 and the cathode 82 are degraded, voltages between the anode 80, the ion exchange membrane 84, and the cathode 82 tend to rise.
A user of the analysis system 100 may acquire the amount and the type of the element contained in at least one of the ion exchange membrane 84, the anode 80, or the cathode 82 by causing the terminal device 10 to be close to at least one of the ion exchange membrane 84, the anode 80, or the cathode 82. With this configuration, the user of the analysis system 100 can acquire the amount of the element without removing at least one of the ion exchange membrane 84, the anode 80, or the cathode 82 from the electrolyzer 90. The user of the analysis system 100 may acquire the amount and the type of the element contained in at least one of the ion exchange membrane 84, the anode 80, or the cathode 82 in a state of being installed in the electrolyzer 90.
The first transmission unit 14 (see
The reception unit 22 (see
The state analysis unit 24 analyzes a state of the object 110 based on the amount of the element which is received by the reception unit 22. When the object 110 is the ion exchange membrane 84, the state of the object 110 may be a state of ion exchange performance of the ion exchange membrane 84. When the ion exchange performance of the ion exchange membrane 84 is degraded, a current efficiency of the electrolyzer 90 may fall. The current efficiency is set as a current efficiency CE. The current efficiency CE may refer to a current efficiency of the electrolyzer 90, or may refer to a current efficiency of the ion exchange membrane 84.
The current efficiency CE refers to a ratio of an actual amount of production to a theoretical amount of production of a product which is to be produced by the electrolyzer 90. The product is set as a product P. A theoretical amount of production of the product P is set as an amount of production Pa. An actual amount of production of the product P is set as an amount of production Pr. The current efficiency CE refers to a ratio of the amount of production Pr to the amount of production Pa.
When the ion exchange performance of the ion exchange membrane 84 is degraded, the voltage of the electrolyzer 90 may rise. The voltage is set as a voltage CV. The voltage CV may be a voltage per one electrolytic cell 91 (see
When the ion exchange performance of the ion exchange membrane 84 is degraded, anions of the liquid 73 (see
When the object 110 is the ion exchange membrane 84, an analysis on the state of the object 110 may refer to an identification of a factor causing a fall of the current efficiency CE by analyzing the type and the amount of the element contained in the ion exchange membrane 84, or may refer to an identification of a factor causing a rise of the voltage CV.
When the object 110 is the anode 80 and the cathode 82, the state of the object 110 may be a coating condition of a metal or the like with which the surfaces of the anode 80 and the cathode 82 are coated. When the coating condition of the anode 80 and the cathode 82 are degraded, the voltage CV may rise. When the object 110 is the anode 80 and the cathode 82, the analysis of the state of the object 110 may refer to an identification of a factor causing a rise of the voltage CV by analyzing types and amounts of the elements contained in the anode 80 and the cathode 82.

The state analysis unit 24 (see
The second transmission unit 27 transmits an analysis result of the state of the object 110 which is analyzed by the state analysis unit 24 to the information terminal 30. The analysis result is set as an analysis result Ra. The second transmission unit 27 may wirelessly transmit the analysis result Ra to the information terminal 30. The analysis result Ra may be displayed on the display unit 32.
In the present example, the amount of an element contained in the object 110 which has been acquired by the element acquisition unit 12 in the terminal device 10 is transmitted to the server 20 by the first transmission unit 14, and in the server 20, the state of the object 110 is analyzed by the state analysis unit 24 based on the amount of the element. Thus, the user of the analysis system 100 can recognize the analysis result Ra without a delivery of a sample of the object 110 for analyzing the state from the location Sb to the location Sa. As compared with a case where the sample of the object 110 is delivered from the location Sb to the location Sa, a period of time from an acquisition of the amount of the element contained in the object 110 to a calculation of the analysis result Ra is more likely to be shortened.
In the present example, the analysis result Ra is transmitted to the information terminal 30 by the second transmission unit 27. Thus, a user of the electrolyzer 90 can immediately recognize the analysis result Ra based on the amount of the element which is acquired by the terminal device 10 by looking at the display unit 32. The user of the electrolyzer 90 can operate the electrolyzer 90 while looking at the analysis result Ra.
The operating condition acquisition unit 23 acquires an operating condition of the electrolyzer 90. The operating condition is set as an operating condition Cd. The operating condition Cd refers to an operating situation of the electrolyzer 90 which may affect the state of the object 110. The operating condition Cd may include a current supplied to the electrolyzer 90, the current efficiency CE of the electrolyzer 90, the voltage CV of the electrolyzer 90, a pH and a flow rate of the liquid 70 (see
The operating condition Cd may be continually acquired, or may be periodically acquired. For example, the periodical acquisition refers to a continual acquisition at a predetermined time interval such as a daily acquisition from 8:00 in the morning to 20:00 in the evening or a continual 8-hour acquisition every three days.
The storage unit 25 may store the operating condition Cd acquired by the operating condition acquisition unit 23, and the type and the amount of the element contained in the object 110. When the electrolyzer 90 is operated under a plurality of operating conditions Cd, the storage unit 25 may store the type and the amount of the element for each of the plurality of operating conditions Cd. The storage unit 25 may further store the analysis result Ra.
Note that a configuration may be adopted where the operating condition Cd is not acquired by the operating condition acquisition unit 23. The storage unit 25 may store the operating condition Cd inputted by the user of the analysis system 100.
In the present example, the plurality of electrolyzers 90 are arranged in mutually different locations. In the present example, an electrolyzer 90-1 is arranged in a location Sb1, an electrolyzer 90-2 is arranged in a location Sb2, and an electrolyzer 90-m is arranged in a location Sbm. Where m is an integer greater than or equal to 2.
The location Sb1 to the location Sbm may be mutually different geographical locations. The location Sb1 is, for example, a predetermined city in United States, the location Sb2 is, for example, a predetermined city in Europe, and the location Sbm is, for example, a predetermined city in Australia. In the present example, a terminal device 10-1 and an information terminal 30-1 are arranged in the location Sb1, a terminal device 10-2 and an information terminal 30-2 are arranged in the location Sb2, and a terminal device 10-m and the information terminal 30-m are arranged in the location Sbm.
In the present example, each of the element acquisition units 12 in the plurality of terminal devices 10 respectively acquires the amount of the element contained in each of the plurality of objects 110. The reception unit 22 in the server 20 receives the amount of the element which is acquired by each of the element acquisition units 12 in the plurality of terminal devices 10. In the present example, each of the first transmission units 14 in the plurality of information terminals 30 respectively transmits the amount of the element contained in each of the plurality of objects 110, and the reception unit 22 receives each of the amounts of the elements which are transmitted by the first transmission units 14.
The state analysis unit 24 in the server 20 analyzes a state of one of the objects 110 based on the amount of the element which has been acquired by each of the element acquisition units 12 in the plurality of terminal devices 10 and received by the reception unit 22. In the present example, the state analysis unit 24 analyzes the state of one of the objects 110 based on each of the amounts of the elements which has been transmitted by each of the first transmission units 14 in the plurality of information terminals 30 and received by the reception unit 22. One of the objects 110 refers to any one or more of the objects 110 of the electrolyzer 90-1 to the electrolyzer 90-m.
The storage unit 25 may store the respective operating conditions Cd in the plurality of electrolyzers 90 and the type and the amount of the element contained in each of the plurality of objects 110. The storage unit 25 may store the operating condition Cd and the type and the amount of the element for each of the plurality of electrolyzers 90.
The state analysis unit 24 may calculate the first relationship R1 (see
The state analysis unit 24 may analyze the state of one of the ion exchange membranes 84 based on the amount of the element which is received by the reception unit 22 and the first relationship R1 stored in the storage unit 25. With this configuration, the user of the analysis system 100 can recognize the state of one of the ion exchange membranes 84 which has been compared with a state of another of the ion exchange membranes 84. In the present example, since the reception unit 22 receives the amount of the element which is transmitted by the first transmission unit 14 in each of the plurality of information terminals 30, the reception unit 22 can receive the amounts of the elements of the objects 110 in the electrolyzers 90 arranged to be mutually separated by a long distance, and also the state analysis unit 24 can analyze the state of one of the ion exchange membranes 84. Thus, the user of the analysis system 100 can recognize the analysis result Ra without delivery of a sample of the object 110 to analyze the state from each of the plurality of locations Sb to the location Sa. The calculation of the analysis result Ra by the state analysis unit 24 is facilitated as compared with a case where the sample of the object 110 is delivered from each of the plurality of locations Sb to the location Sa.
Similarly, the state analysis unit 24 may analyze the state of one of the ion exchange membranes 84 based on the amount of the element which is received by the reception unit 22 and the second relationship R21 stored in the storage unit 25. Similarly, the state analysis unit 24 may analyze the state of one of the anodes 80 or the cathodes 82 based on the amount of the element which is received by the reception unit 22 and the second relationship R22 stored in the storage unit 25.
Each of the plurality of element acquisition units 12 may further acquire identification information for identifying the object 110 in one of the electrolyzers 90 and the object 110 in another of the electrolyzers 90 among the plurality of electrolyzers 90. The identification information is set as identification information Id. When the object 110 is the ion exchange membrane 84, the identification information Id may be a type of the ion exchange membrane 84. The type of the ion exchange membrane 84 may be a physical quantity which may be different for each of individual ion exchange membranes 84, such as a density of an anion group 86 (see

The storage unit 25 may store the operating condition Cd, the type and the amount of the element, and the identification information Id for each of the plurality of electrolyzers 90.
The storage unit 25 may further store, with regard to the plurality of electrolyzers 90 arranged at mutually different locations, a plurality of pieces of location information related to the different locations. In the example of
The storage unit 25 may store the respective operating conditions Cd in the plurality of electrolyzers 90, the types and the amounts of the elements contained in the plurality of objects 110, the identification information Id corresponding to each of the plurality of electrolyzers 90, and the location information related to each of the plurality of electrolyzers 90.

The analysis result Ra illustrated in
To identify a factor for the degradation of the performance of the object 110, the operation of the electrolytic apparatus 200 may be temporarily stopped. A period of time to stop the operation of the electrolytic apparatus 200 is preferably as short as possible. When the terminal device 10 is the portable X-ray fluorescence analysis terminal device, it is facilitated for the user of the electrolytic apparatus 200 to identify the factor for the degradation of the performance of the object 110 without removing the object 110 from the electrolytic apparatus 200, and to take countermeasures for the recovery of the performance of the object 110. Therefore, the period of time to stop the operation of the electrolytic apparatus 200 is more likely to be shortened. Since the user of the electrolytic apparatus 200 may recover the performance of the object 110 without the replacement of the object 110, it is less likely to lose the object 110.

The state prediction unit 26 may predict a time when the object 110 is put into the third state S3 based on the change over time of the amount of the element which is received by the reception unit 22 and the third relationship R3 (see
The third relationship R3 may be determined for each of the identification information Id. The state prediction unit 26 may predict, based on a change over time of an amount of an element in one of the electrolyzers 90 and the third relationship R3 in the one of the electrolyzers 90, a time when the object 110 of the one of the electrolyzers 90 is put into the third state S3, or may predict a time when the object 110 in another of the electrolyzers 90 is put into the third state S3.
The second transmission unit 27 may transmit the time when the object 110 is put into the first state S1, the time when the object 110 is put into the second state S2, or the time when the object 110 is put into the third state S3 which is predicted by the state prediction unit 26 to the information terminal 30. With this configuration, the user of the electrolyzer 90 can recognize the time when the object 110 is put into the first state S1, the time when the object 110 is put into the second state S2, or the time when the object 110 is put into the third state S3.
The state prediction unit 26 may predict the time when the object 110 is put into the first state S1 for each of the types of the elements based on the change over time of the amount of the element which is received by the reception unit 22 and the first relationship R1 (see

A countermeasure to recover the current efficiency CE of the electrolyzer 90 is set as the first countermeasure Cm1. For example, when the current efficiency CE is less than a predetermined value, the first countermeasure Cm1 is a countermeasure based on a factor by which the current efficiency CE is less than the predetermined value, that is a countermeasure to recover the current efficiency CE to be the predetermined value or more by eliminating the factor. For example, when the factor by which the current efficiency CE is less than the predetermined value is an adhesion of a predetermined impurity onto the ion exchange membrane 84, the first countermeasure Cm1 is to remove the impurity from the ion exchange membrane 84.
A countermeasure to recover the voltage CV of the electrolyzer 90 is set as a second countermeasure Cm2. For example, when the voltage CV is above a predetermined value, the second countermeasure Cm2 is a countermeasure based on a factor by which the voltage CV is above the predetermined value, that is a countermeasure to recover the current efficiency CE to be the predetermined value or less by eliminating the factor. For example, when an NaCl (sodium chloride) aqueous solution is inputted into the anode chamber 79 and when a factor by which the voltage CV is above a predetermined value is that the NaCl (sodium chloride) concentration of the aqueous solution is out of a predetermined range, the second countermeasure Cm2 is a countermeasure for the NaCl (sodium chloride) concentration to return to a predetermined range.
A countermeasure to recover the Cl− (chloride ion) concentration of the liquid 75 is set as a third countermeasure Cm3. When a Cl− (chloride ion) concentration of the liquid 75 is above a predetermined concentration, the third countermeasure Cm3 is a countermeasure based on a factor by which the Cl− (chloride ion) concentration is above the predetermined concentration, that is a countermeasure to recover the Cl− (chloride ion) concentration of the liquid 75 to be the predetermined value or less by eliminating the factor. The recovery of the Cl− (chloride ion) concentration to be the predetermined value or less may refer to a fall of the Cl− (chloride ion) concentration to be the predetermined value or less.
The storage unit 25 may store at least one of the first countermeasure Cm1, the second countermeasure Cm2, or the third countermeasure Cm3. When the first countermeasure Cm1 is implemented, the state prediction unit 26 may predict the state of the object 110 in a case where the first countermeasure Cm1 is implemented. The state prediction unit 26 may predict the state of the object 110 in a case where the first countermeasure Cm1 is implemented for each of the operating conditions Cd. The second transmission unit 27 may transmit, to the information terminal 30, the state of the object 110 which is predicted by the state prediction unit 26, that is the state of the object 110 in a case where the first countermeasure Cm1 is implemented.

The state prediction unit 26 may predict the state of the object 110 in a case where the third countermeasure Cm3 is implemented for each of the operating conditions Cd. The second transmission unit 27 may transmit, to the information terminal 30, the state of the object 110 which is predicted by the state prediction unit 26, that is the state of the object 110 in a case where the third countermeasure Cm3 is implemented.

The state analysis unit 24 may analyze the state of the object 110 based on the position of the opening 60 and the position of the element E in the object 110. The position of the opening 60 and the position of the element E may be positions in the side view of the single electrolytic cell 91 (see
The state of the object 110 may depend on the position of the opening 60 and the position of the element E. Thus, since the state of the object 110 is analyzed based on the position of the opening 60 and the position of the element E, the element E bringing about the state of the object 110 is more likely to be identified. The second transmission unit 27 may transmit the analysis result Ra based on the position of the opening 60 and the position of the element E to the information terminal 30.
The first state learning unit 120 generates a first state inference model 122 (described below) through machine learning on a relationship between the current efficiency CE and the amount of the element which is acquired by the element acquisition unit 12 (see
The first inferred state Se1 and the second inferred state Se2 may be the analysis result Ra by the state analysis unit 24. The first state inference model 122 and the second state inference model 132 may be stored in the storage unit 25. The state analysis unit 24 may analyze the state of the object 110 based on at least one of the first state inference model 122 or the second state inference model 132 stored in the storage unit 25.
The element acquisition step S100 is a step for the element acquisition unit 12 to acquire an amount of an element contained in the object 110 in the electrolyzer 90.

The determination step S106 may be a step for the state analysis unit 24 to determine whether the object 110 is the ion exchange membrane 84, or at least one of the anode 80 or the cathode 82. In the determination step S106, the state analysis unit 24 may determine whether the object 110 is the ion exchange membrane 84, or at least one of the anode 80 or the cathode 82 based on the type of the element which is acquired in the element acquisition step S100.
The analysis method of the present example includes a storage step S108 and a storage step S114. When it is determined in the determination step S106 that the object 110 is the ion exchange membrane 84, the storage step S108 may be a step for the storage unit 25 to store the amount of the element which is acquired in the element acquisition step S100.

The intensity acquisition step S110 is a step for the reception unit 22 to acquire an intensity of the X-rays 114 (see
A threshold of the intensity of the X-rays 114 is set as a threshold intensity Stp. The threshold intensity Stp may be previously set for each of the types of the elements. The determination step S112 is a step for the state analysis unit 24 to determine whether the intensity of the X-rays 114 which is acquired in the intensity acquisition step S110 is the threshold intensity Stp or more. When it is determined in the determination step S112 that the intensity of the X-rays 114 is the threshold intensity Stp or more, the analysis method proceeds to step S200. When it is determined in the determination step S112 that the intensity of the X-rays 114 is less than the threshold intensity Stp, the analysis method proceeds to step S300.
In the state analysis step S109, the state analysis unit 24 may analyze the state of the object 110 (in the present example, the ion exchange membrane 84) based on the predetermined first relationship R1 between the current efficiency CE of the electrolyzer 90 and the amount of the element, or may analyze the state of the object 110 (in the present example, the ion exchange membrane 84) based on the predetermined second relationship R21 between the voltage CV of the electrolyzer 90 and the amount of the element. In the present example, in the determination steps S200 to S212, the state analysis unit 24 analyzes the state of the object 110 (in the present example, the ion exchange membrane 84) by determining whether the intensity of the X-rays 114 is the threshold intensity Stp or more for each of predetermined elements. In the present example, the predetermined elements are Ni (nickel), Ca (calcium), Sr (strontium), Ba (barium), I (iodine), Fe (iron), and Zr (zirconium).
When the object 110 is at least one of the anode 80 or the cathode 82, the state analysis step S109 of the present example has an intensity acquisition step S116. The intensity acquisition step S116 is a step for the reception unit 22 to acquire the intensity of the X-rays 114 (see

The analysis method of the present example further includes a proposal step S220. The proposal step S220 is a step of proposing an examination item, a countermeasure, or the like to the user of the electrolyzer 90 with regard to the element in which the intensity of the X-rays 114 is the threshold intensity Stp or more. The countermeasure may be at least one of the first countermeasure Cm1, the second countermeasure Cm2, or the third countermeasure Cm3 described above.
The comparison step S300 is a step for the state analysis unit 24 to compare the analysis result Ra of one of the objects 110 with the analysis result Ra of another of the objects 110. The one of the objects 110 may be the object 110 set as an analysis target. The another of the objects 110 may be the object 110 related to a past analysis result Ra. With this configuration, the user of one of the electrolyzers 90 can recognize the analysis result Ra of the state of the object 110 of one of the electrolyzers 90 which has been compared with the analysis result Ra of the object 110 in another of the electrolyzers 90.

The second transmission step S304 may be a step for the second transmission unit 27 to transmit, to the information terminal 30, the time when the object 110 is put into the first state S1 or the time when the object 110 is put into the second state S2 which is predicted in the state prediction step S302.
A display step S306 is a step for the display unit 32 in the information terminal 30 to display the analysis result Ra. With this configuration, the user of the electrolyzer 90 can recognize the analysis result Ra. The display step S306 may be a step for the display unit 32 in the information terminal 30 to display the time when the object 110 is put into the first state S1 or the time when the object 110 is put into the second state S2. With this configuration, the user of the electrolyzer 90 can recognize the time when the first state S1 is established or the time when the second state S2 is established.
