Abstract
An electrode for fuel cell is made of a solid polymer electrolyte-catalyst composite electrode containing a cation-exchange resin, carbon particles and a catalyst metal. The catalyst metal is loaded mainly on the surface of the carbon particles in contact with the proton-conductive passage in the cation-exchange resin. Preferably, the catalyst metal has a nucleus containing a metal (X) and an outer layer containing a metal (Y) which is not contained in the nucleus.
