<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of efficiently conducting purge by conducting purge while the humidity degree is measured. <P>SOLUTION: The fuel cell system 1 has a temperature measuring cell 10 in which a plurality of temperature sensors 25, 26, 27 are installed along the flow direction of purge gas, and when purge is conducted, purge gas is made to flow for the prescribed time to the fuel cell stack 2, the humidity degree in each position in the gas flow direction inside a fuel cell cell is detected based on a rate of change with time of temperature measured with the temperature sensors 25, 26, 27, and when the rate of change with time of temperature is smaller than the prescribed value, purge is stopped. <P>COPYRIGHT: (C)2007,JPO&INPIT |
