PURPOSE:To provide a solid electrolyte type fuel cell having a solid electrolytic body which is superior in its electrochemical properties and mechanical strength. CONSTITUTION:A solid electrolytic body 1 is equipped with a fuel electrode 3 and an air electrode 4 on its front and back faces, respectively. The solid electrolytic body 1 is composed of a partially stabilized zirconia member 1a as a base and stabilized zirconia films 1b formed on the front and back faces of the member 1a. The air electrode 4 and the stabilized zirconia film 1b are in contact with each other, and warping and debonding at co-sintering can be prevented by only adding a small quantity of Mn to the partially stabilized zirconia member 1a, whose proportion is the same as Mn added to the stabilized zirconia film 1b. |
