PURPOSE:To obtain a fuel cell in which a deterioration in the performance is prevented even after long time operation by arranging a specified film on an oxygen electrode, and separating stabilized zirconia from the oxygen electrode with this film. CONSTITUTION:A separating film comprising In2O3-SnO2 or In2O3-ZnO (the content of SnO2 or ZnO is 1-10 molar percent) is arranged on an oxygen electrode. By this film, stabilized zirconia is separated from La1-xM<1>M<2>O3-X/2 to prevent the contact. The thickness of the separating film is specified to 10mum or less to reduce the internal resistance of a cell. In the formula, M11 is Sr, Mg, Ca, or Ba, and M<2> is Co, Fe, or Mn, and x is a number larger than zero but smaller than 1. |
