PROBLEM TO BE SOLVED: To reduce leakage currents running toward a fuel electrode from an air electrode through an interconnector with little change in the structure of the interconnector.SOLUTION: The present invention includes: an air electrode 31 and a fuel electrode 32 joined to each other through an interconnector 1, which is formed from metal oxide with oxygen ion conductivity, and a protective layer 11 positioned between the air electrode 31 and the interconnector 1 and formed from conductive material with lower oxygen reduction catalyst activity than the air electrode 31. |
