A system for warming a fuel cell stack is provided to allow the warm air discharge from a stack to be circulated in enclosure in case of cooling starting, to increase the operation temperature of a stack by cooling water and to allow the stack to be operated under optimized condition within a short time. A system for warming a fuel cell stack comprises a stack(100) which has a manifold(M) where hydrogen, air, cooling water and reaction product water flow, an air inlet and an air outlet formed at the both sides, and a temperature sensor(200A) installed inside; an enclosure warming region(300) which surrounds the entire outside of the stack and has a recirculation path so as to circulate the air discharged from the stack in case of the cooling starting inside the installed enclosure; and a controller(700) which is inputted with the temperature sensed from the temperature sensor in case of the cooling starting to recirculate the air discharged from the stack to the enclosure warming region, thereby increasing the temperature of the stack. |
