PURPOSE:To prevent the generation of warp and/or tear at the joint of an interconnector with a spacer in the process of co-sintering. CONSTITUTION:A solid electrolyte 1 is provided consisting of stabilized zirconia (YSZ), and an air electrode 2 and fuel electrode 3 are furnished at the oversurface and undersurface of this solid electrolyte 1. These electrodes 2, 3 are furnished over the surfaces with a distributor 5 made of (La0.8Sr0.2)MnO3 and a distributor 6 made from a hybrid material of NiO and YSZ, respectively. On both sides of these distributors 5, 6, spacers 7, 8 are arranged consisting of CaTiO3. Over and below thereof interconnectors 10, 11 are provided consisting of (La0.7-Ca0.3)CrO3. If these components are subjected to co-sintering, no Ca diffusion takes place from the interconnectors 10, 11 to the spacers 5, 6. |
