METHOD FOR MANUFACTURING FUEL ELECTRODE-SOLID ELECTROLYTE LAYER COMPOSITE
To provide a fuel electrode-solid electrolyte layer composite excellent in ion conductivity and ion transport number.SOLUTION: A method for manufacturing a fuel electrode-solid electrolyte layer composite includes: a first step of obtaining a precursor in which a porous first solid electrolyte layer and a second solid electrolyte layer having a smaller porosity than the first solid electrolyte layer are integrated; and a second step of imparting catalyst particles into pores of the first solid electrolyte layer of the precursor. The second step includes firing the precursor at temperatures of 200-1,100°C, after a dispersion including the catalyst particles dispersed therein has been contained in the pores.SELECTED DRAWING: Figure 2
