PURPOSE:To adjust with a cooling fluid the temp. of an object to cool, particular ly an object of a high temp. CONSTITUTION:A cooling fluid passing through a cooling means has dissolved therein a boiling point conditioner which changes the boiling point of the cooling fluid according to its concentrations, a temp. detecting means 73 for detecting the temp. of an object O to be cooled and a concentration adjusting means D for adjusting the concentration of the boiling point conditioner are provided and a control means M is further provided to control the concentration adjusting means D based on the detection information of the temp. detecting means 73 so as to bring the temp. of the object O close to a predetermined temp. The object O refers to a fuel cell F provided with the cell having an oxygen electrode on one side of its electrolytic layer and a fuel electrode on the other side. |
