<P>PROBLEM TO BE SOLVED: To provide a fuel cell system for keeping temperature distribution of a cell constant even in the case an operation mode of the fuel cell is changed. <P>SOLUTION: In this fuel cell system FCS, a coolant is supplied into the fuel battery cell stack FS, and a coolant supply/discharge part is equipped which discharges the coolant out of the fuel battery cell stack FS. That coolant supply/discharge part includes a first coolant discharge part 51 having a first discharge pipe 451 to discharge the coolant by being extended from the fuel battery cell stack FS and a first manifold 401 arranged in the fuel battery cell stack FS and linked to the first discharge pipe 451, and a second coolant supply/discharge part 52 having a second discharge pipe 452 to discharge the coolant by being extended from the fuel battery cell stack FS, and a second manifold 402 arranged in the fuel battery cell stack FS, and linked to a second discharge pipe 452, and the first discharge pipe 451 is constituted of a material higher in thermal expansion coefficient than the second discharge pipe 452. <P>COPYRIGHT: (C)2010,JPO&INPIT |
