Abstract:
A fuel cell has an anode, a cathode, and a solid electrolyte layer. The cathode contains a main component configured by a perovskite oxide which is expressed by the general formula ABO 3  and includes at least one of La and Sr at the A site. The solid electrolyte layer is disposed between the anode and the cathode. The cathode includes an interface region that is within 5 μm from a surface near to the solid electrolyte layer. The interface region contains a main phase configured by the perovskite oxide, and a secondary phase configured by strontium oxide. An occupied surface area ratio of the secondary phase in a cross section of the interface region is greater than or equal 0.05% and less than or equal to 3%.

Claim (Index 2):
The fuel cell according to  claim 1 , wherein an average equivalent circle diameter of the secondary phase in a cross section of the interface region is greater than or equal to 10 nm and less than or equal to 500 nm.
