PROBLEM TO BE SOLVED: To provide a manufacturing method wherein, in order to improve the electrode characteristics of a fuel pole, a mixed conductor is guided to the vicinity of an interface with an electrolyte, with no occurrence of degraded material. SOLUTION: A fuel pole and a solid electrolyte are baked. An electrode active oxide containing both electron conduction and oxygen ion conduction is infiltrated, as an organic metal solution or inorganic metal salt solution, into the porous fuel pole. Then by a thermal decomposition oxidative reaction, the electrode active oxide of a desired composition is guided to the vicinity of an interface with the solid electrolyte. Thus, the fuel pole for a solid electrolyte fuel cell of high performance is provided with no strict limit on a baking process. |
