PURPOSE:To provide a solid electrolyte fuel cell type power generator furmace preventing gas from leaking from a partition wall between an air chamber and a fuel gas chamber allowing a cell-stack to pass through in a freely movable manner. CONSTITUTION:In a chamber with lower pressure, an air chamber 16 or a fuel gas chamber 6, a green compact 16 made from a perovskite lanthanum composite oxide is installed while cold with a predetermined distance L from a partition wall 3 and around that side of a cell-stack 7 toward which the partition wall 3 is moved by thermal expansion. At least that side 3a of the partition wall 3 which faces the green compact 16 is also made from the perovskite lanthanum composite oxide. When the power reactor is in steady operation at about 1000 deg.C the partition wall 3 approaches the green compact 16; when gas leaks from the space between the green compact 16 and the partition wall 3 and temperature rises the green compact 16 is connected to the partition wall 3 by sintering so that the space is blocked. |
