METHOD FOR MANUFACTURING SOLID OXIDE FUEL CELL AND SOLID OXIDE FUEL CELL

摘要

A method is provided for manufacturing a solid oxide fuel cell having excellent power generation performance and thermal cycle resistance and a solid oxide fuel cell. A method for manufacturing a solid oxide fuel cell includes a first step ST11 of sequentially forming a fuel electrode and a solid oxide electrolyte layer on a substrate; a second step ST12 of forming an air electrode intermediate layer on the solid oxide electrolyte layer; and a third step ST13 of forming, on the air electrode intermediate layer, an air electrode conductive layer using a mixture obtained by mixing first particles in a first average particle size range in which the average particle size (d50) is in a range of 27.0 μm to 31.0 μm and second particles in a second average particle size range having an average particle size (d50) smaller than the first average particle size range.
