▎ 摘　　要

NOVELTY - A catalyst for fuel cells comprises support (10); first catalytic active material (20) supported on the support and comprising a platinum component comprising one or more selected from platinum and platinum alloy; and second catalytic active material (30) supported on the support and comprising one or more selected from a noble metal other than platinum and its oxide. Support comprises functional groups comprising oxygen. USE - A catalyst for fuel cells (claimed). ADVANTAGE - The catalyst may induce water electrolysis rather than carbon corrosion when cell voltage reversal occurs in a fuel cell. High contents of catalytic active materials are uniformly supported on a support in the catalyst. The catalyst has excellent durability which increases binding force between a support and catalytic active materials to maintain activity even under severe conditions, such as cell voltage reversal. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of a catalyst for fuel cells, which involves preparing a solution comprising a noble metal other than platinum; putting a support on which a platinum component comprising one or more selected from platinum and platinum alloy is supported into the solution; loading the noble metal other than platinum on the support; and oxidizing the noble metal other than platinum loaded on the support, where the support comprises functional groups comprising oxygen. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the catalyst for fuel cells. Support (10) First catalytic active material (20) Second catalytic active material (30)
