<P>PROBLEM TO BE SOLVED: To suppress the lowering of the performance of a fuel cell by preventing the dissolution of a noble metal particle. <P>SOLUTION: The fuel cell electrode material formed on the front surface and/or the back surface of an electrolyte material film 1 as an fuel cell electrode, has a catalyst particle formed by including a noble metal particle 2 containing Pt into a porous inorganic material 3, and a proton conductive material. The noble metal particle 2 is included into the porous inorganic material 3, so that Pt is prevented from dissolving into the electrolyte material film 1 and the degradation of the performance of the fuel cell caused by the dissolution of Pt into the electrolyte material film 1 is suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
