PROBLEM TO BE SOLVED: To stop cooling liquid of high conductivity from flowing into a fuel cell. SOLUTION: With the cooling method of the fuel cell 1 in which heat accompanying power generation of the fuel cell 1 is radiated with a radiator 4 by circulation of cooling liquid, an ion exchanger 5 for removing ions existing in the cooling liquid is installed in a cooling liquid circulation system, by which, a part of the cooling liquid is circulated between the radiator 4 and the ion exchanger 5 to remove ions in the cooling liquid in the heat exchanger 5 when temperature of the cooling liquid is lower than predetermined, and the cooling liquid is circulated between the fuel cell 1 and the heat exchanger 4 to cool down the fuel cell 1 when temperature of the cooling liquid is bigbur than predetermined. |
