ABSTRACT:
A cathode for electrolysis, particularly of a sodium chloride aqueous solution by an ion-exchange membrane method, and a process for producing the same, the cathode comprising a conductive base having a nickel surface and having provided thereon (a) at least one platinum group component selected from the group consisting of a platinum group metal, a platinum group metal oxide, and a platinum group metal hydroxide, and (b) at least one cerium component selected from the group consisting of cerium, cerium oxide, and cerium hydroxide, retaining a markedly reduced hydrogen overpotential for an extended period of time and exhibiting excellent resistance to impurities in the electrolytic solution.
