<P>PROBLEM TO BE SOLVED: To provide a fuel electrode for a fuel battery which allows the improvement of the structural reliability against thermal stress, and a manufacturing method and a material which are suitable for the production of the fuel electrode. <P>SOLUTION: The fuel electrode 3 comprises at least a structure 31, and an electron conductor 32. The structure 31 has a core part 311, and a surface layer 312 covering the outer periphery of the core part 311. The core part 311 includes an oxygen ion conductor as its primary component, and the surface layer 312 includes a proton conductor as its primary component. The fuel electrode 3 can be manufactured by baking a mixture of at least a kind of powder formed from the structure 31, and a kind of powder formed from the electron conductor 32, provided that the structure has: the core part 311 including an oxygen ion conductor as its primary component; and the surface layer 312 covering the outer periphery of the core part 311 and including a proton conductor as its primary component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
