<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell prevented from gas-leak at a junction part of a power generation part and a frame part. <P>SOLUTION: A unit cell 7 is formed by interposing a flat-plate-shaped solid electrolyte 1 between a fuel electrode 3 and an air electrode 5, and a frame 9 is jointed to an outer peripheral part of the unit cell 7 by using a jointing material 23. A convex part 9a protruding toward the solid electrolyte 1 is formed at the inside end part of the frame 9. Deterioration of the jointing material 23 is prevented by preventing the jointing material 23 from being exposed to an oxidative atmosphere of high temperature at air electrode 5 side by the convex part 9a. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
