Title:
ELECTRODE FOR HYDROGEN GENERATION, PROCESS FOR PRODUCING THE SAME AND METHOD OF ELECTROLYSIS THEREWITH
Document Type and Number:
WIPO Patent Application WO/2005/103337
Kind Code:
A1
Abstract:
An electrode for hydrogen generation that has satisfactorily low hydrogen overpotential and is free from any influence of poisoning by iron ions and that is free from any increase of hydrogen overpotential or dropout of carried material during operation or at startup or stopping, excelling in durability; a process for producing the hydrogen generation electrode; and a method of electrolysis in which the electrode for hydrogen generation is used as a negative electrode. Use is made of an electrode for hydrogen generation comprising a conductive base material and, carried thereon, a platinum alloy composed of platinum and a metal selected from the group consisting of nickel, cobalt, copper, silver and iron, or an amorphous material of transition metal element and platinum. This electrode can be obtained by performing coating with a solution of compound of metal selected from the group consisting of nickel, cobalt, copper, silver and iron and a solution of platinum compound capable of forming an ammine complex, drying them and conducting pyrolysis at 200 to 700&ring C, optionally followed by reduction treatment.
