Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell equalizing flow rate of exhausted fuel gas, and preventing cracks, etc., caused by heat spots. SOLUTION: In this fuel cell, intermediate current-collecting plates 15 having exhaust pipes 11 which pass exhausted fuel gas are provided in gaps 22 between adjacent cells 7 and between the endmost cells and a bulkheads. Ceramic fibers 13 are filled between the exhaust pipes 11, and cells 7 and the bulkheads. Thus, the flow paths of the exhaust gas are provided, which equalizes combustion in combustion chambers so as to eliminate heat spots. Thus, thermal shocks to the cells can be relaxed.
