<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack device that contributes to reduction in power generation unevenness in a stacking direction of cells by suppressing an excessive temperature drop at an end cell positioned at an end in the stacking direction of the stack. <P>SOLUTION: A refrigerant passage structure 7 of a stack 1 includes intermediate refrigerant passages 70 of intermediate cells 2C present in the middle in the stack direction, and end refrigerant passages 72, 73 of end cells 2E, 2F present at ends in the stack direction. A refrigerant supplied from a refrigerant supply passage 5 to an entrance is flown to the intermediate refrigerant passages 70 of the intermediate cells 2C to cool the intermediate cells 2C, and the refrigerant which flows in the intermediate refrigerant passages 70 and receives heat from the intermediate cells 2C to be made warm is flown to the end refrigerant passages 72, 73 to cool the end cells 2E, 2F. <P>COPYRIGHT: (C)2012,JPO&INPIT |
