Pure hydrophobic carbon is produced by the thermal decomposition of polyvinylidene chloride. A porous carbon electrode for use in a fuel cell may be formed by compressing polyvinylidene powder at 10 tons/sq. in. to form a pellet and the compressed material carbonized at a temperature of 200-1,350 DEG C. in air, helium, nitrogen, hydrogen, or a mixture of hydrogen and nitrogen. The electrode may be coated with palladium, platinum, nickel, cobalt, rhodium, iron, copper, gold, silver, cadmium, or molybdenum. The metal may be deposited by electro or vapour deposition or by decomposition of an impregnated salt. |
