PURPOSE:To obtain a solid electrolyte fuel cell having high performance by providing a fine electrolyte molding on one surface of an air pole molding, which is obtained by molding the slurry, and burning this compound molding to obtain a solid electrolyte-air pole compound, and providing a porous fuel electrode on the other surface of this solid electrolyte-air pole compound. CONSTITUTION:Zirconia powder, to which yttria as stabilizer is added, dispersant, binder, untifoaming agent, and LaMnO3 which is doped with strontium as metal oxide are mixed with water solvent to obtain the slurry-shape mixture, and this slurry is filled in a mold 4 made of the material having the water absorbing property such as gypsum, and it is left to mold an air pole molding 1. Next, at the time of molding an air pole 5 from this molding 1, the mold 4 is removed, and the molding 1 is dipped in the slurry to generate an even electrolyte molding 2 on the peripheral surface of the molding 1. Next, this compound molding is burned to form a solid electrolyte-air pole compound, which has the air pole 5 inside of the molding 2 and the solid electrolyte 6 outside thereof, and a fuel electrode 7 is provided in the film 6 side. |
