PROBLEM TO BE SOLVED: To cool the cell stack of a fuel cell appropriately, without performing temperature adjustment of oxidized gas supplied to the fuel cell.SOLUTION: A fuel cell module includes a battery side thermal insulation material 2 for separating the internal space of a pressure vessel 205 into the outer space 5 and the inner space 6, a plurality of cell stacks 101 arranged in the inner space 6, and a lower damper 11-i. In the battery side thermal insulation material 2, a plurality lower passages 7 connecting the lower parts of the outer space 5 and inner space 6, and an upper passage 8 connecting the upper parts of the outer space 5 and inner space 6 are formed. A lower damper 11-i adjusts the flow rate of a gas flowing from the outer space 5 to the inner space 6 via the plurality lower passages 7, and flowing from the inner space 6 to the outer space 5 via the plurality upper passages 8. In such a fuel cell, the plurality of cell stacks 101 can be cooled appropriately, by adjusting the flow rate of a gas convecting the outer space 5 and inner space 6.SELECTED DRAWING: Figure 5 |
