Abstract
A fuel cell stackincludes a plurality of fuel cellsin which a fuel electrode, a solid oxide electrolyte, and an air electrodeare sequentially laminated, an interconnectorthat electrically connects the fuel cellswhich are adjacent to each other, and an interconnector connecting layerthat is interposed directly between the air electrodeand the interconnector. The interconnector connecting layeris formed from a material, which is expressed by a composition formula of (LaSrCa)MnO-AppmSiO-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.
