摘要： PROBLEM TO BE SOLVED: To provide means for substantially increasing catalyst activity and/or increasing gas distribution in carbon carriers to substantially prevent the increase in fuel cell gas diffusion resistance in connection with an electrode catalyst for a fuel cell.SOLUTION: The present invention relates to an electrode catalyst for a fuel cell, which comprises: carbon carriers having pores; and catalyst particles including platinum or a platinum alloy and supported by the carbon carriers. The pores of the carbon carriers have a pore mode size in a range of 2.1-5.1 nm. As to the pores of the carbon carriers, the total pore volume is in a range of 21-35 cm/g. The distance between the catalyst particle and the surface of the carbon carriers is in a range of 2.0-12 nm, which is a distance at 50%-cumulative frequency.SELECTED DRAWING: Figure 1

摘要： This invention is intended to improve the coverage of a platinum or platinum alloy surface with gold when producing a catalyst comprising carrier particles that support gold-modified platinum or platinum alloys. The invention provides a method for producing a catalyst comprising carrier particles that support gold-modified platinum or platinum alloys comprising a step of gold reduction comprising adding carrier particles that support platinum or platinum alloys, a reducing agent, and a gold precursor to a liquid medium and mixing the same, wherein the reducing agent is added to adjust the ORP value (i.e., an oxidation-reduction potential with reference to the silver-silver chloride electrode) of the liquid medium to -630 to +230 mV upon completion of addition.
