Catalyst for solid polymer fuel cell and method for producing the same |
| abstract |
The present invention relates to a catalyst for a solid polymer fuel cell in which catalyst particles composed of platinum and transition metal M are supported on a carbon powder carrier. The catalyst of the present invention is a catalyst for a solid polymer fuel cell, characterized in that the molar ratio (Pt/M) of platinum and transition metal M constituting catalyst particles is 2.5 or more, and the platinum measured by the CO adsorption method is characterized in that The ratio (S COMSA /S BET ) of the specific surface area (S COMSA ) to the catalyst specific surface area (S BET ) measured by the BET method is 0.26 or more and 0.32 or less. This catalyst can be produced by washing the alloy catalyst with a platinum compound solution after preparing the alloy catalyst and additionally supplementing platinum on the surface of the catalyst particles. |
