To provide electrode catalyst for a fuel cell with high catalytic activity capable of suppressing dissolution of non-precious metal contained in the catalyst and with improved service life characteristic in the catalyst.
The electrode catalyst for the fuel cell has alloy particulates composed of precious metal and non-precious metal carried on a conductive carrier such as carbon powder, fiber or a substrate by a pulse electolytic method. As an example, an apparatus 1a is composed of a depositing side electrode 11 providing a place for carrying alloy particles 3 by conducting current to the conductive carrier 2, an electrode couple 12, and a constant voltage DC power source 13 capable of making potential constant between the two electrodes. Electrolyte solution 14 is contained in a container with precious metal ion and non-precious metal ion.
