PROBLEM TO BE SOLVED: To provide a cooling controller of a fuel cell system in which power consumption can be reduced while cooling a fuel cell well.SOLUTION: A target rotation speed of a water pump 66 is set so that the temperature difference between a temperature detected by an FC inlet fuel temperature sensor 30 and a temperature detected by an FC outlet fuel temperature sensor 32, i.e., the temperature difference between the temperature of a liquid supplied from a fuel supply pipe 28 to a fuel inlet 12 and the temperature of a liquid discharged from a fuel outlet 13 to a fuel discharge pipe 31, falls within a range (allowable range) equal to or higher than a predetermined release temperature and equal to or lower than a switching temperature. Driving of the water pump 66 is controlled based on the target rotation speed. |
