Claims
- 1. A water electrolyzer, comprising:
- a. an anode electrode;
- b. an anode chamber formed by a first screen set superimposed on said anode electrode;
- c. a cathode electrode;
- d. a cathode chamber formed by a second screen set superimposed on said cathode electrode;
- e. an ion exchange membrane disposed between and in intimate contact with said anode electrode and said cathode electrode; and
- f. a porous sheet constructed and arranged for dual directional flow and for supporting said ion exchange membrane, said porous sheet interposed between said first screen set and said anode electrode.
- 2. A water electrolyzer as in claim 1 further comprising a second porous sheet for supporting said ion exchange membrane interposed between said second screen set and said cathode electrode.
- 3. A water electrolyzer as in claim 1 further comprising a fine mesh screen for supporting said ion exchange membrane interposed between said second screen set and said cathode electrode.
- 4. A water electrolyzer as in claim 1 wherein said porous sheet is carbon, niobium, tantalum, titanium, zirconium, or mixtures thereof.
- 5. A water electrolyzer as in claim 1 wherein said porous sheet has a mean pore size between about 10 microns and about 14 microns and has a porosity between about 40% and about 60%.
- 6. A water electrolyzer as in claim 1 wherein said porous sheet is electroplated with platinum.
- 7. A water electrolyzer, comprising:
- a. an anode electrode;
- b. an anode chamber formed by a first screen set superimposed on said anode electrode;
- c. a cathode electrode;
- d. a cathode chamber formed by a second screen set superimposed on said cathode electrode;
- e. an ion exchange membrane disposed between and in intimate contact with said anode electrode and said cathode electrode;
- f. a porous sheet constructed and arranged for dual directional flow and for supporting said ion exchange membrane, said porous sheet interposed between said second screen set and said cathode electrode.
- 8. A water electrolyzer as in claim 7 wherein said porous sheet is carbon, niobium, tantalum, titanium, zirconium, or mixtures thereof.
- 9. A water electrolyzer as in claim 7 wherein said porous sheet has a mean pore size between about 10 microns and about 14 microns and has a porosity between about 40% and about 60%.
- 10. A water electrolyzer as in claim 7 wherein said porous sheet is electroplated with platinum.
- 11. A water electrolyzer as in claim 7 further comprising a fine mesh screen for supporting said ion exchange membrane interposed between said anode electrode and said first screen set.
