PURPOSE:To provide a cell of a solid electrolyte fuel cell with stability over a long period of time and high fraction of nondefective. CONSTITUTION:A metal oxide solid electrolyte 3 and a porous fuel electrode 4 made of a metal-metal oxide composite body are stacked in order on the surface of a cylindrical porous air electrode 2 made of LaMnO3 base solid solution, and a current collector 5 made of a conductive metal oxide is stacked on part of the air electrode to constitute a cell of a fuel cell. An intermediate layer 6 resistant to a halogen gas and made of a perovskite composite oxide represented by (La1-x-yAxBy)z(Cr1-pCp)O3+ or -DELTA wherein A is a 3a group element in the periodic table, B is an alkali earth element, C is Mn, Ni, Fe, Ce, or Zr, and x, y, z, and p are in the specified range, is interposed between the air electrode and the solid electrolyte, or between the air electrode and the current collector. The solid electrolyte and the current collector are manufactured without adverse effect on the function of the air electrode, and the cell with high performance can be manufactured. |
