PURPOSE:To provide a highly reliable solid electrolyte fuel cell by preventing the rupture of a cell while heightening adaptability to differential thermal expansion when a temperature is raised or lowered, and also carrying out effective gas seal in gas seal structure for the solid electrolyte fuel cell. CONSTITUTION:In lower partition plates 30 to which support bodies 25 constituting solid electrolyte fuel cells are fixed so as to partition a gas passage, double- stepped grooves 30-1 having a projecting shape part 30-3 are formed in parts in which the support bodies 25 are installed, and gas seal materials 1 composed of low melting point alloy are filled in these grooves 30-1. Thereby, the gas seal materials 1 are made to keep a melting condition up to a temperature at which influence is not exerted upon cell members due to thermal expansion when a temperature is raised or lowered, so that the rupture of a cell and so on caused when the temperature is raised or lowered can be prevented. |
