Berchielli, A S; Chireau, R F

An improved hydrogen electrode comprises a porous sheet of carbon particles catalyzed by platinum or palladium and bonded together with a hydrophobic binder, preferably Teflon, so that the sheet is wetproofed. A conductive metallic screen coated on one side with a hydrophobic binder is laminated on the coated side to the sheet. A battery comprising a stack of the improved hydrogen electrodes, preferably with conductive metallic spacers between the screen of each cell and the cathode of the next adjacent cell forming a bipolar duplex electrode with hydrogen flow passageways to the screen-covered face of each anode, is stacked together with an electrolyte-filled separator provided between the bipolar electrodes. The improved hydrogen anode is the anode of the duplex electrode, while the cathode of the duplex electrode may be a material such as a porous sintered nickel or silver plaque. The conductive means joining the anode and cathode comprises the metallic screen with or without the metallic spacer present.
