| 摘要 |
An electrode material for fuel cell superimposed on the top and/or back of electrolyte membrane (1) as an electrode for fuel cell, which electrode material comprises catalyst particles, the catalyst particles composed of Pt - containing precious metal particles (2) enclosed in porous inorganic materia l (3), and a proton conducting substance. As the precious metal particles (2) are enclosed in the porous inorganic material (3), elution of Pt into the electrolyte membrane (1) can be avoided and any performance deterioration of the fuel cell attributed to the elution of Pt into the electrolyte membrane (1) can be inhibited. |
