Catalyst for solid polymer electrolyte fuel cells and method for producing same |
| abstract |
The present invention pertains to a catalyst for solid polymer electrolyte fuel cells, wherein catalyst particles composed of platinum and transition metal M are supported on a carbon powder carrier. This catalyst for solid polymer electrolyte fuel cells is characterized in that the molar ratio (Pt/M) between platinum and transition metal M which constitute catalyst particles is at least 2.5, and the ratio (S COMSA /S BET ) of the specific surface area (S COMSA ) of platinum as measured by the CO adsorption method to the specific surface area (S BET ) of the catalyst as measured by the BET method is 0.26-0.32. This catalyst can be produced by preparing an alloy catalyst and then washing the alloy catalyst with a platinum compound solution, and further replenishing the surfaces of catalyst particles with platinum. |
