PURPOSE:To provide a solid electrolyte fuel cell wherein an interconnector and an air pole side distributer can be sintered together without being separated. CONSTITUTION:An air pole side distributer 5 composed of (La0.7Ca0.3)MnO is joined via a joint part 5a to an interconnector composed of (La0.7Ca0.3)CrO3. The joint part 5a is composed of material in which the composition ratio between (La0.7Ca0.3)MnO and (La0.7Ca0.3)CrO3 is made different stepwise. Namely, the joint part 5a is formed by stacking nine (9) kinds of green sheets made of material expressed by a formula of (La0.7Ca0.3) (Cr1-XMNX)O3, where (X) is 0.1 to 0.9 set by 0.1. The contraction rate at each temp. at the baking process of the joint part 5a has a value between the contraction rate of distributer 5 and the contraction rate of interconnector 10, and becomes that of stepwise inclined type. |
