PURPOSE:To improve a sealing property of the peripheral part of an electrode base material by filling the peripheral part of the electrode base material with gel of a phosphate compound. CONSTITUTION:Zirconium phosphate gelatinized by adding phosphoric acid fills the peripheral part of a fuel electrode base material 8, or the wet sealing part 9, for instance, by press fitting. Zirconium phosphate is gelatinized while being dissolved in phosphoric acid when a sufficient amount of phosphoric acid is existing while otherwise being solidified. In either case, zirconium phosphate snows a fully excellent gas sealing property as compared with the case where former SiC is used for filling. |
