Abstract
A cathode for electrolysis comprising a hydrogen-occluding material for use in an electrolytic cell partitioned by the cathode into two chambers including a reaction chamber and an electrolysis chamber. The cell is arranged so that a reactant is reduced or hydrogenated in the reaction chamber. The cathode comprises an ion exchange membrane or porous membrane. A first layer made of a hydrogen-occluding metallic palladium or a palladium alloy is formed on the reaction chamber side of the membrane. A second layer which is a porous catalyst layer made of a platinum metal black or gold is formed on the first layer. Also disclosed is an electrolytic cell using the cathode for electrolysis.
