Abstract
In a cooling device for a fuel cell, a primary cooling liquid discharged from a heat exchange device is partially flowed to an ion exchange device through a communication passage B. A flow rate regulator provided in the communication passage B regulates the flow rate of the primary cooling liquid flowed into the ion exchange device . 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.
