PURPOSE:To enhance power generating efficiency by eliminating a fuel gas leak in a fuel cell. CONSTITUTION:A groove 8 is installed on the surface, on the side of a fuel electrode 5a, of a solid electrolyte 4 and on the side of a separator 7a so as to surround the fuel electrode 5a. An alloy tube 2 in which a gas which is a thermal expansion material is press-sealed is fitted in the groove 8, and pressed from the both sides of the separator 7a and the solid electrolyte 4. |
