Abstract

A method for producing an electrode catalyst for a fuel cell is provided. The electrode catalyst includes a carbon support and a catalyst supported on the carbon support. The catalyst is one of platinum and a platinum-alloy. The method includes supporting the catalyst on the carbon support; and treating the carbon support carrying the catalyst with a nitric acid and cleaning the treated carbon support, such that an amount of an acid present on the carbon support becomes in a range from 0.7 mmol to 1.31 mmol of the acid per gram of the electrode catalyst.
