<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of shortening the next starting time and inhibiting to degrade a fuel cell stack by eliminating differential pressure even in a case that pressure drops because of temperature change of the system and condensation of water vapor or the like. <P>SOLUTION: In the fuel cell system, a controller 21 closes a blocking valve 3 provided on a fuel gas feeding route 11 for feeding fuel gas to the fuel cell stack 1 and a purge valve 5 for discharging dopant accumulated in redundant fuel gas discharged from the fuel cell stack 1 to the outside at the time of stopping the fuel cell system and opens the purge valve 5 in accordance with a predetermined condition. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
