PROBLEM TO BE SOLVED: To reduce a spread in a temperature distribution of the whole cell stack group comprising a plurality of cell stacks.SOLUTION: A plurality of cell stacks 101 forming a solid oxide fuel cell are regularly arranged at a predetermined interval therebetween, and includes a plurality of central cell stacks 6 arranged in a central region 1 and a plurality of outside cell stacks 5 arranged in an outside region 3 surrounding the central region 1. Here, the plurality of central cell stacks 6 are decimated at a decimation part 7 in the central region 1, and thus more oxidizing gas flows through the decimation part 7 in the central region 1. Accordingly, the plurality of central cell stacks 6 can be cooled more than the plurality of outside cell stacks 5 by the oxidizing gas, so that the spread of a temperature difference between the plurality of cell stacks 101 can be suppressed.SELECTED DRAWING: Figure 5 |
