    摘要: An object of the present invention is to provide a platinum catalyst for a fuel cell, the platinum catalyst having platinum particles with a fine particle size which are supported 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 fuel cell, the method comprising: an ammonia treatment step of heat-treating carbon carriers in an ammonia gas atmosphere; a platinum salt contact step of mixing the carbon carriers treated with ammonia with a solution prepared by dissolving a platinum salt in a solvent and bringing the platinum salt coming into contact with the carbon carriers in the mixture that has been formed; a recovery step of recovering the carbon carriers by removing the solvent from the mixture; and a heat treatment step of heat-treating the recovered carbon carriers in an inert gas atmosphere.
