<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack device advantageous to warming a stack in the circumferential direction. <P>SOLUTION: This fuel cell stack device is provided with: the stack 1 formed by stacking a plurality of separators 2 and a plurality of membrane-electrode assemblies 5 in the thickness direction; cooling medium passages 6 formed in the stack 1 for running a cooling medium for cooling the stack 1; and heat-retaining passages 7 formed outside the cooling medium passages 6 for running a heat-retaining medium. Each heat-retaining passage 7 is formed in the separator 2 and arranged in the plane direction and in the circumferential direction of the separator 2 in the peripheral side of the cooling medium passage 6, whereby the heat-retaining medium is run along the plane direction and in the circumferential direction of the separator 2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
