PROBLEM TO BE SOLVED: To easily and accurately measure temperature of the interior of a fuel cell stack in which multiple power generation units are laminated and prevent a cooling medium from being flowed unavailingly.SOLUTION: A fuel cell stack 10 is formed by laminating multiple power generation units 12. A cooling medium circulation feeding device 98 comprising the fuel cell stack 10 includes: a coolant medium communication passage 35, which is in communication with a coolant medium passage 44, is provided separately from a cooling medium inlet communication hole 34a and a cooling medium outlet communication hole 34b so as to have a small opening cross section area, and penetrates through in the lamination direction; and a drain side temperature detector 112 detecting the temperature of the coolant medium discharged from the coolant medium communication passage 35. A drain valve 114 is placed in a drain passage 110, and the drain passage 110 is connected to a reserve tank 116. |
