<P>PROBLEM TO BE SOLVED: To provide the temperature control method of a fuel cell stack structure enhancing durability by suppressing the generation of stress concentration by reducing the temperature difference between the large part of heat capacity and the small part of it in a stage from starting to stop, and to provide the fuel cell stack structure. <P>SOLUTION: In the fuel cell stack structure 1 formed by stacking a plurality of solid oxide fuel cells 10 having solid oxide type unit cells 11 housed in a space S surrounded by metallic thin plate-like separators 12, 13 and exposing the one surface to the outside, and supplying gas from a gas passage 2 passing through the solid oxide fuel cell 10 to each space S of the solid oxide fuel cell 10, a thermocouple 32 is installed in a plurality of portions, and the heat quantity balance in each portion is controlled so as to make the temperature distribution uniform based on temperature information from the thermocouple 32. <P>COPYRIGHT: (C)2007,JPO&INPIT |
