A method for producing a catalyst for a fuel cell which comprises a step of mixing an organic solvent containing a surfactant and an aqueous solution containing an iridium compound, to form a reversed micelle, wherein the above aqueous solution containing an iridium compound is included by the above surfactant, a step of converting the iridium compound to an insoluble material, to thereby form agglomerates of fine iridium-containing particles, a step of impregnating the above agglomerates of fine iridium-containing particles with an aqueous solution containing a platinum compound, a step of reducing the above platinum compound and precipitating a platinum metal inside the above agglomerates of fine iridium-containing particles to thereby prepare a fluid containing a reversed micelle, wherein agglomerates of fine iridium-containing particles containing platinum are included, a step of dispersing an electroconductive carrier in the above fluid, to form the above agglomerates of fine iridium-containing particles containing platinum carried on the above electroconductive carrier, and a step of firing the above electroconductive carrier having the above agglomerates of fine iridium-containing particles containing platinum carried thereon. |
