As shown in FIG. 5, a fuel electrode 12 and a solid electrolyte 13 were integrally fired, and an electrode was attached using platinum 14 to form an evaluation test cell. This cell was subjected to tests of the AC impedance method and the current interrupt method in a reducing atmosphere at 1000 ° C.

Therefore, the porosity of the sample used for the evaluation test is larger than the porosity at the time of firing the fuel electrode sample.

FIG. 7 shows the relationship between the resistance value obtained by adding the diffusion resistance and the reaction resistance obtained by the current interrupt method and the porosity after reduction of the sample. From the results of these two evaluation tests, the relationship between the diffusion resistance and reaction resistance of the fuel electrode and the porosity can be estimated as shown in FIG. In this example, the diffusion resistance and the reaction resistance of the fuel electrode were minimized in the sample whose porosity after reduction was around 30%.
