Abstract
The present invention is to provide a catalyst for fuel cells, which is able to inhibit gas diffusion resistance and shows high IV characteristics far more than conventional fuel cell catalysts, and a method for producing the catalyst. Disclosed is a catalyst for fuel cells, comprising fine catalyst particles, each of which comprises a palladium-containing particle and an outermost layer containing platinum and covering the palladium-containing particle, and a carrier on which the fine catalyst particles are supported, wherein the catalyst for fuel cells satisfies 0.9×S1≤S2 in which S1 is a BET specific surface area of a material for the carrier, and S2 is a BET specific surface area of the carrier in the catalyst for fuel cells.
