<P>PROBLEM TO BE SOLVED: To provide a solid oxide type fuel cell that can be miniaturized and thinned, and prevents a module from being damaged by thermal stress generated when temperature rises due to operation or when temperature decreases due to stop, to provide a cooling method of the solid oxide type fuel cell, and to provide a solid oxide type fuel cell system. <P>SOLUTION: In the fuel cell 1, a gas supply pipe 7 having an air supply and exhaust hole 7a for supplying and exhausting fuel or air is provided at a through hole 55 formed at the outer-periphery of an interconnector 3 with a gap 58 for stacking. Then, the fuel cell 1 is composed so that the outer-periphery surface of the gas supply pipe 7 adheres to the inner-periphery surface of the through hole 55 at operating temperature. At the operating temperature, the outer-periphery surface of the gas supply pipe 7 and the inner-periphery surface of the through hole 55 are caulked and adhered due to the thermal expansion of the gas supply pipe 7 and the interconnector 3, thus preventing the gas supply pipe 7 and the interconnector 3 from being damaged by thermal expansion. <P>COPYRIGHT: (C)2008,JPO&INPIT |
