PROBLEM TO BE SOLVED: To provide a highly durable fuel electrode supporting solid oxide fuel cell having a high output density, the strength of which is less likely to lower even if the fuel cell is exposed repeatedly to reduction atmosphere/oxidation atmosphere.SOLUTION: A fuel electrode supporting solid oxide fuel cell 100 has a fuel electrode 10, a solid oxide electrolyte film 20, an air electrode 30. The fuel electrode 10 includes a porous structure consisting of a solid oxide, and an aggregate of electrode particles having electrode catalytic ability and dispersed into the cavities of the porous structure. In the plan view of the fuel electrode 10 from the exposed surface of the solid oxide electrolyte film 20, the porous structure and the aggregate of electrode particles are distributed in patchy, and the area of the porous structure to that of the fuel electrode is 10-50% in the plan view. |
