Patent ID: 10454123

Abstract:
A metal-supported cell comprises a laminate wherein a fuel electrode layer and a solid electrolyte layer are sequentially arranged in this order on a front surface of a metal support provided with a pore continuing from the front surface to the back surface. The solid electrolyte layer covers all parts of the surface of the fuel electrode layer, the parts being not in contact with the metal support. The peripheral part of the solid electrolyte layer is in contact with the front surface of the metal support. The metal support has a metal oxide layer. The fuel electrode layer contains NiO and Ni with molar ratio NiO/(Ni+NiO) of 45% or more, while containing gadolinium-doped ceria. The solid electrolyte layer mainly contains scandia-stabilized zirconia, while containing 0.1-10.0 mol of Bi atoms per 100 mol of Zr atoms having cross-sectional void fraction of 5.0% or less.
