Patent ID: 7871740

Claim:
An electrode for a fuel cell, comprising a catalyst layer, wherein the catalyst layer comprises a catalyst composite and a binder, where the catalyst composite comprises a proton-conductive inorganic oxide and an oxidation-reduction catalyst phase, the proton-conductive inorganic oxide comprising a catalyst carrier comprising at least one material selected from the group consisting of tin(Sn)-doped In 2 O 3 , fluorine(F)-doped SnO 2 , and antimony(Sb)-doped SnO 2 and an amorphous oxide particle phase chemically bonded to a surface of the catalyst carrier and comprising at least one element selected from the group consisting of tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V), and boron (B), the oxidation-reduction catalyst phase being supported, directly or through the amorphous oxide particle phase, on the catalyst carrier.
