| Abstract | A cathode/membrane assembly for an electrolysis cell capable of producing hydrogen in a cathode compartment, utilizes as the cathode material on a proton-permeable solid-electrolite ion-exchange membrane, a layer of porous graphite in the form of carbonaceous fibers coated with tungsten carbide. The graphite felt can be impregnated with an aqueous solution of para-ammoniumtungstate or with an alcoholic solution of tungsten hexachloride and the tungsten compounds are then converted to the tungsten oxides. The tungsten oxide coated graphite felt is then subjected to carburization at a temperature of 620 DEG to 950 DEG C. in a carburizing atmosphere, preferably a flowing CO/CO2 mixture. |
