ELEKTROCHEMISCHE WASSERSTOFFZELLE UND IHRE VERWENDUNG IN EINER WIEDERAUFLADBAREN METALL/WASSERSTOFF-BATTERIE

摘要

An improved hydrogen electrode comprising 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 relectrodes. 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.
