An electrolytic cell bank comprising two end plate electrodes, a plurality of intermediate electrodes, a plurality of dielectric separators spaced between the electrodes to form electrolytic cell chambers, a plurality of gas separator diaphragms, alkaline electrolyte, manifolds for allowing off-gas withdrawal of hydrogen and oxygen and means for back-pressuring the exterior walls of each end plate to counter-balance pressures developed within the electrolytic cell chambers. The cell bank is utilized to convert water into its constituent gases of oxygen and hydrogen, and the cell bank is sufficiently large to commercially produce hydrogen at pressures equal to the pressures utilized in commercial gas transmission lines.

A bank of electrolytic cell for electrolytically converting water into its constituent gases of hydrogen and oxygen upon the application of a voltage source comprising: two end plate electrodes, a plurality of intermediate electrodes spaced between said end plate electrodes, a plurality of dielectric separators individually spacing and electrically separating adjacent electrodes from one another and together with the said electrodes forming impervious electrolytic cell chambers between adjacent electrodes, pressure developing in said chamber during the converting of water into hydrogen and oxygen, a plurality of gas separator diaphragms individually spaced between adjacent electrodes to divide each said electrolytic cell chamber into two sections to prevent the remixing of hydrogen and oxygen, alkaline electrolyte contained in each cell chamber, means for connecting a voltage source to said electrodes, means for introducing water to each of said electrolytic cell chambers, first manifold means connected with like sections of each of said electrolytic cell chambers for allowing off-gas withdrawal of hydrogen, first automatic valve means for closing said first manifold whenever the pressure within said electrolytic cell chambers is equal to or less than a preselected pressure, second manifold means connected with the other like sections of each electrolytic cell chambers for allowing off-gas withdrawal of oxygen, second automatic valve means for closing said second manifold means whenever pressure within said electrolytic cell chambers is equal to or less than preselected pressure, means for back-pressuring the exterior walls of each end plate electrode to counter-balance any pressure developed within the adjacent electrolytic cell chambers and exerted against the inside wall of the end plate electrodes.
