ABSTRACT:
A low hydrogen overvoltage cathode is provided which comprises an electroconductive base material coated with an alloy layer containing cobalt and tin at least at a content of tin ranging from 0.01 to 95% by weight. A process is also provided for producing the low hydrogen voltage cathode, wherein cobalt and tin at least are electrolytically co-deposited onto a surface of an electroconductive base material from a plating bath containing cobalt ions, tin ions, and a complexing agent.
