ABSTRACT:
Highly active hydrogen evolving cathode using a platinum group metal catalyst in an amount smaller than that used in the conventional hydrogen evolving cathode. The hydrogen evolving cathode includes a conductive substrate, and a catalyst layer comprising at least one selected from the group consisting of silver and a silver oxide compound, and at least one selected from the group consisting of a platinum group metal, a platinum group metal oxide and a platinum group metal hydroxide, formed on a surface of the conductive substrate.
