    摘要： A fuel cell, which can supply stable output even at elevated temperatures and can maintain its power generation performance over a long period of time, can be realized by an electrode for a fuel cell comprising a catalyst layer formed of a catalyst composite and a binder, the catalyst composite comprising a proton-conductive inorganic oxide and an oxidation-reduction catalyst phase supported on the proton-conductive inorganic oxide, the proton-conductive inorganic oxide comprising a catalyst carrier selected from tin(Sn)-doped In2O3, fluorine(F)-doped SnO2, and antimony(Sb)-doped SnO2 and an oxide particle phase chemically bonded to the surface of the catalyst carrier. The catalyst composite is manufactured by dispersing a catalyst carrier in a solution containing a material as a starting material for an oxide particle phase, heat treating the dispersion to form a proton-conductive inorganic oxide, further dispersing the proton-conductive inorganic oxide in a catalyst precursor-containing solution, and subjecting the dispersion to heat treatment or pH adjustment to deposit a catalyst phase.
