In a cooling device for a fuel cell, a primary cooling liquid discharged from a heat exchange device 3 is partially flowed to an ion exchange device 15 through a communication passage 11B. A flow rate regulator 14 provided in the communication passage 11B regulates the flow rate of the primary cooling liquid flowed into the ion exchange device 15. Accordingly, even if the electricity demanded to be outputted from the fuel cell increases or decreases, it is possible to manage conductivity in the primary cooling liquid and useless consumption energy can be reduced to a minimum.
