Electrodes for fuel cell and processes for producing the same

摘要

An electrode for a fuel cell of the invention comprises a cation-exchange resin, carbon particles and a catalyst metal which is amorphous. The electrode has high activity, a high catalyst utilization and high CO tolerance and is highly active in the electrochemical oxidation reaction of methanol. Furthermore these qualities of the electrode were extremely improved when the catalyst metal was loaded mainly on sites where the surface of the carbon particles contacts proton-conductive passages in the cation-exchange resin. Consequently, a fuel cell with the electrode of the invention has a high output current and a long life, and can be produced at low cost.
