PROTON-CONDUCTIVE INORGANIC MATERIAL FOR FUEL CELL AND FUEL CELL ANODE EMPLOYING THE SAME |
摘要 |
The present invention aims to provide a fuel cell anode, a membrane electrode assembly and a fuel cell, so as to obtain high electric power. The fuel cell anode has an electrode catalyst layer, and the electrode catalyst layer comprises a supported catalyst comprises electrically conductive carriers and fine catalytic particles supported thereon, a proton-conductive inorganic oxide supporting SiO2 on its surface, and a proton-conductive organic polymer binder. The SiO2 supported on the inorganic oxide prevents the oxide particles from growing, to ensure the high electric power. It is necessary to control the mixing ratios among the supported catalyst, the proton-conductive oxide and the proton-conductive binder in particular ranges. |
