Claims
- 1. A liquid fuel tank comprising:a storing portion located in the tank for storing a liquid fuel comprising water and alcohol; a liquid outlet port provided in the tank; a connecting section for connecting the tank to a fuel cell; a liquid permeating material arranged in said connection section; and a pressure adjusting mechanism for maintaining a constant pressure within said tank and for permitting a required amount of the liquid fuel to be discharged from said liquid outlet port to a location outside the tank.
- 2. The liquid fuel tank according to claim 1, wherein said pressure adjusting mechanism comprises a selectively permeable membrane mounted to a predetermined region of an outer wall of the tank.
- 3. The liquid fuel tank according to claim 1, wherein said pressure adjusting mechanism comprises a fine hole made through a predetermined region of the outer wall of the tank.
- 4. The liquid fuel tank according to claim 1, further comprising a liquid absorbing material which is arranged within said tank for guiding the liquid fuel to said liquid outlet port and a gas pathway arranged within the tank for introducing into the tank a gas generated outside the tank.
- 5. The liquid fuel tank according to claim 1, further comprising a liquid absorbing material arranged on an inner wall of the tank in contact with the liquid outlet port, at least a part of said liquid absorbing material being kept in contact with said liquid fuel.
- 6. The liquid fuel tank according to claim 1, further comprising a pressure mechanism positioned within the liquid fuel tank for guiding the liquid fuel to the liquid outlet port, and for maintaining contact between the liquid fuel and the liquid outlet port.
- 7. The liquid fuel tank according to claim 1, wherein said pressure adjusting mechanism comprises a mechanism for preventing an excessively high pressure in the liquid fuel tank, and wherein said mechanism comprises a pressure release valve mounted to the tank.
- 8. The liquid fuel tank according to claim 1, wherein at least a part of said tank is formed of a transparent or semi-transparent material.
- 9. A liquid fuel tank comprising:a storing portion located in the tank storing a liquid fuel comprising water and alcohol; a liquid outlet port formed in the tank; a slidable connecting section for connecting the tank to a fuel cell; a tapered-angle central shaft arranged within said slidable connecting section; and a pressure adjusting mechanism for maintaining a constant pressure within said tank so as to permit a required amount of the liquid fuel to be discharged from said liquid outlet port to a location outside the tank.
- 10. The liquid fuel tank according to claim 9, wherein said pressure adjusting mechanism comprises a selectively permeable membrane mounted to a predetermined region of an outer wall of the tank.
- 11. The liquid fuel tank according to claim 9, wherein said pressure adjusting mechanism comprises a fine hole made through a predetermined region of an outer wall of the tank.
- 12. The liquid fuel tank according to claim 9, further comprising a liquid absorbing material arranged within said tank for guiding the liquid fuel to said liquid outlet port and a gas pathway arranged within the tank and for introducing a gas into the tank generated outside the tank.
- 13. The liquid fuel tank according to claim 9, further comprising a liquid absorbing material arranged on an inner wall of the tank in contact with the liquid outlet port, at least a part of said liquid absorbing material being kept in contact with said liquid fuel.
- 14. The liquid fuel tank according to claim 9, further comprising a pressure mechanism positioned within the tank for guiding the liquid fuel to the liquid outlet port, and for maintaining contact between the liquid fuel and the liquid outlet port.
- 15. The liquid fuel tank according to claim 9, wherein said pressure adjusting mechanism includes a mechanism for preventing an excessively high pressure in the tank, said mechanism comprises a pressure release valve mounted on tank.
- 16. The liquid fuel tank according to claim 9, wherein at least a part of said liquid fuel tank comprises one of a transparent material and a semi-transparent material.
- 17. A liquid fuel tank storing a liquid fuel for a fuel cell, comprising a pressure adjusting mechanism connected to the tank for maintaining a constant pressure within said tank so as to permit a required amount of the liquid fuel to be discharged from a liquid outlet port on an outside portion of the tank and a storage section, said storage section comprises one of said liquid fuel tank and a tank for storing the liquid fuel, said tank having a rotary mechanism for keeping the liquid fuel at a level above said liquid outlet port.
- 18. The liquid fuel tank according to claim 17, wherein said pressure adjusting mechanism comprises a selectively permeable membrane mounted to a predetermined region of an outer wall of the tank.
- 19. The liquid fuel tank according to claim 17, wherein said pressure adjusting mechanism comprises a fine hole formed in a predetermined region of an outer wall of the liquid fuel tank.
- 20. The liquid fuel tank according to claim 17, further comprising a liquid absorbing material which is arranged within said tank for guiding the liquid fuel to said liquid outlet port and a gas pathway arranged within the tank for introducing a gas into the tank generated outside the tank.
