PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electrolyte fuel cell that produces high output due to low contact resistance between a solid electrolyte membrane and an air electrode, and a solid electrolyte fuel cell.SOLUTION: A fuel electrode 13, a solid electrolyte membrane 14, and an interconnector 16 are formed on a substrate tube 11, and then sintered together. An air electrode intermediate layer 15a mainly composed of a ceria compound represented by SmCeO, where 0.8≤x≤0.9, is formed on the solid electrolyte membrane 14 and the interconnector 16 sintered together. An air electrode conductive layer 15b represented by LaSrCaMnO, where y>1, 0.4≤a≤0.8, 0.4≤b≤0.8, in which the ratio of the total number of moles of La, Sr, and Ca to the number of moles of Mn is higher than or equal to 0.92 and lower than or equal to 0.98, is formed on the air electrode intermediate layer 15a. Mn in the air electrode conductive layer 15b is diffused into the air electrode intermediate layer 15a by sintering the air electrode intermediate layer 15a and the air electrode conductive layer 15b. |
