<P>PROBLEM TO BE SOLVED: To easily start a fuel cell at a low temperature. <P>SOLUTION: Antifreezing fluid which is refrigerant in a cooling system 13 of a fuel cell stack 1 is once recovered into a tank 136 when starting power generation under low temperature environment to reduce heat capacity of the fuel cell stack 1 and then start power generation. Antifreezing fluid is filled again after recovering to a temperature of normal operation by reaction heat generated by power generation to drive the cooling system 13 and make it function as a cooling means. <P>COPYRIGHT: (C)2003,JPO |
