A fuel cell stack 101 includes a plurality of fuel cells 105 in which a fuel electrode 109, a solid oxide electrolyte 111, and an air electrode 113 are sequentially laminated, an interconnector 107 that electrically connects the fuel cells 105 which are adjacent to each other, and an interconnector connecting layer 108 that is interposed directly between the air electrode 113 and the interconnector 107. The interconnector connecting layer 108 is formed from a material, which is expressed by a composition formula of (La1-x-ySrxCay)zMnO3-AppmSiO2-DppmMgO (provided that, 0<x≦0.4, 0<y≦0.4, 0.1≦x+y≦0.5, 0.95≦z<1, A: 10 to 300, D: 10 to 400), through firing.
A fuel cell stack, comprising:
A method of manufacturing a fuel cell stack including a plurality of fuel cells in which a fuel electrode, a solid oxide electrolyte, and an air electrode are sequentially laminated, and an interconnector that electrically connects the fuel cells which are adjacent to each other, the method comprising:
A high-temperature water vapor electrolysis cell stack, comprising:
A method of manufacturing a high-temperature water vapor electrolysis cell stack including a plurality of electrolysis cells in which a hydrogen electrode, a solid oxide electrolyte, and an oxygen electrode are sequentially laminated, and an interconnector that electrically connects the electrolysis cells which are adjacent to each other, the method comprising:
