PROBLEM TO BE SOLVED: To provide an interconnector fine at such a temperature as exerting no damage to any battery composing material by fining the interconnector for providing connection between single elements by means of a slurry co- sintering method in a solid electrolytic fuel cell. SOLUTION: Oxide powder in which each nitrate of La, Sr, Cr is doped in LaCrO3 group perovskite type oxide is used for the interconnector of a solid electrolytic fuel cell. Or, furthermore, YSZ(yttria stabilized zirconium) is mixed in this powdery material. This mixed powder is formed in a disc shape, etc., and pressurized, and then sintered by the slurry co-sintering method. In this way, an interconnector with high relative density can be obtained. When PSZ or TiO is mixed is LaCrO3 group oxide in which alkaline earth metal is doped, fine substance can be obtained by sintering. Furthermore, by composing them in a mixture consisting of LaCrO3 group material and aluminum phosphate, hydrogen gas leakage quantity can be reduced under their operational condition. |
