PROBLEM TO BE SOLVED: To provide a cooling system.SOLUTION: The cooling system may include: a pump for circulating cooling water to a cooling water line that passes a fuel cell stack; heating means which receives driving power supply from a drive motor of a vehicle, is disposed on the cooling water line and heats the cooling water; and a controller by which, if a heat generation amount of the fuel cell stack is smaller than a first threshold value and a speed of rotation of the pump is equal to or higher than a second threshold value, the heating means is driven with surplus power that is generated by power generation of the drive motor and if the heat generation amount of the fuel cell stack is smaller than the first threshold value and the speed of rotation of the pump is lower than the second threshold value, the heating means is turned off.SELECTED DRAWING: Figure 5
