<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of precisely monitoring the temperature of fuel cell, even when operation of the fuel cell stops, by suppressing the energy consumption, as much as possible. <P>SOLUTION: The fuel cell system comprises a fuel cell 10, a cooling liquid circulating device (20, 21) for supplying and circulating the cooling liquid to the fuel cell 10, and a temperature detection means 22 for detecting the temperatures of the cooling liquid. The system has a cooling liquid circulation driving control means 30 (S5, S6, S7) for driving the cooling liquid circulation device intermittently, when operation of the fuel cell 10 is stopped and a temperature acquisition means 30 (S8) which obtains the temperature of the cooling liquid detected by the temperature detection means 22 as the temperature of the fuel cell; while the cooling liquid circulation device is driven by the cooling liquid circulation drive control means 30. <P>COPYRIGHT: (C)2007,JPO&INPIT |
