PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell including an interconnector having good conductivity and excellent in long term stability.SOLUTION: A solid oxide fuel cell includes a plurality of single elements and an interconnector for electrically connecting the plurality of single elements to each other. The interconnector has a layered structure including a first layer and a second layer. The first layer comprises a material having a composition represented by SrATiO(where, A represents a rare earth element and x satisfies 0<x≤0.2.) or represented by SrATiO(where, A represents a rare earth element and x satisfies 0<x<0.5.), and the second layer comprises a material having a composition represented by SrBTiO(where, B represents a rare earth element and y satisfies 0.2<y<0.5.). |
