摘要：An object of the present invention is to provide a platinum catalyst for a fuelcell, the platinum catalyst having platinum particles with a fine particle size which aresupported on carbon carriers in a highly dispersed manner. To achieve the above object,the present invention provides a method for producing an electrode catalyst for a fuelcell, the method comprising: an ammonia treatment step of heat-treating carbon carriersin an ammonia gas atmosphere; a platinum salt contact step of mixing the carbon carrierstreated with ammonia with a solution prepared by dissolving a platinum salt in a solventand bringing the platinum salt coming into contact with the carbon carriers in the mixturethat has been formed; a recovery step of recovering the carbon carriers by removing thesolvent from the mixture; and a heat treatment step of heat-treating the recoveredcarbon carriers in an inert gas atmosphere.
