Title: Square form permeable electrodes for pressure electrolysis process units
Claims: What is claimed is: 1. An apparatus comprising multiple square form permeable electrodes equally divided into alternate opposite cathodes and anodes, each electrode being one hollow porous metal piece and having a wall thickness not less than 0.007 inch and not more than 0.010 inch, a square non-permeable thin plate bonded and sealed to the bottom of each of said electrodes, a top pressure plate for accurately locating and mounting each of said multiple square form permeable electrodes into precise alternate opposite rows and columns of anodes and cathodes, bonding and sealing means joining each of said multiple square form permeable electrodes into said top pressure plate, a process tank of rectangular form containing all said multiple square form permeable electrodes, and sealing means joining said top pressure plate into said process tank of rectangular form. 2. The apparatus according to claim 1, in which all of said cathodes are made of pure sintered nickel metal with a porosity of 0.5 micron, all of said anodes are made of pure sintered nickel metal with a porosity of 1 micron, said multiple square form permeable electrodes being mounted near one end therefore into said top pressure plate, and the short protruding ends of said multiple square form permeable electrodes above said top pressure plate being sealed to prevent gas leakage. 3. The apparatus according to claim 1, wherein each of said cathodes and anodes is provided with a sub-surface anti-clogging plastic layer on the inside surfaces thereof. 4. The apparatus according to claim 1, in which all of said cathodes are connected to a negative electrical lead from an external low-voltage D.C. power source, all of said anodes are connected to a positive electrical lead from the same external low-voltage D.C. power source, and terminal and insulation means for the electrical leads are provided. 5. The apparatus according to claim 1, wherein each electrode is made from four elongated flat rectangular porous metal pieces joined and sealed at the four corners. 6. Multiple elongated square form permeable electrodes each comprised of fine wire mesh sieve cloth of 400 mesh size made in one rectangular piece for pressure-electrolysis process units, said fine wire mesh sieve cloth of 400 mesh size having three vertical folds to form a square box-like pattern, a vertical elongated core framework consisting of four vertical members with uniformly spaced horizontal ribs disposed between said four vertical members, two joining tabs disposed at the ends of said fine wire mesh sieve cloth of 400 mesh size for joining and sealing around said core framework, bonding and sealing means securing said fine wire mesh sieve cloth of 400 mesh size around said vertical elongate core framework to form said electrode, a bottom square non-permeable thin plate bonded and sealed to the bottom of each of said formed electrode. 7. Multiple elongated square form permeable electrodes according to claim 6, in which the said wire mesh sieve cloth is made of fine monel wire. 8. Multiple elongated square form permeable electrodes according to claim 6, in which fine short length cross wire whiskers are randomly disposed at right angles into the grid openings of said fine wire mesh sieve cloth, said cross wire whiskers are nearly 0.0015 inch in diameter to closely fit into the grid openings of said fine wire mesh sieve cloth. 9. Multiple elongated square form permeable electrodes according to claim 6, in which half of said electrodes are connected to a negative electrical lead from an external low-voltage D.C. power source as cathodes, and the other half of said electrodes are connected to a positive electrical lead from the same external low-voltage D.C. power source as anodes. 10. An apparatus wherein the electrodes of claim 6 are mounted near one end thereof into a top pressure plate, bonding and sealing means joining each of the electrodes to said top pressure plate, the short protruding ends of said electrodes being sealed to prevent gas leakage, a process tank of rectangular form and open at the top containing said electrodes, sealing means joining said top pressure plate to said process tank, and an anti-clogging plastic coating for each of said multiple square form permeable electrodes uniformly disposed over all exposed surfaces.
