The present invention provides an excellent durable cathode for hydrogen generation, which has a low hydrogen overvoltage and reduced dropping-off of a catalyst layer against the reverse current generated when an electrolyzer is stopped, and a method for producing the same. The present invention provides a cathode for hydrogen generation having a conductive base material and a catalyst layer formed on the conductive base material, wherein the catalyst layer includes crystalline iridium oxide, platinum and iridium-platinum alloy.

Cathode for hydrogen generation and method for producing the same

An electrode catalyst comprising a conductive carrier, and a mixture containing a particulate noble metal and at least one particulate rare-earth oxide, the mixture being supported on the conductive carrier wherein the particulate rare-earth oxide has an alkaline-earth metal as solid solution therein.
