<P>PROBLEM TO BE SOLVED: To provide a fuel cell system correctly controlling a purge amount. <P>SOLUTION: In this fuel cell system for exhausting an anode off-gas by opening/closing a purge valve 18 arranged in an anode off-gas supply passage 15 of a fuel cell 10, a purge amount is calculated on the basis of a pressure difference ΔP(t) between anode off-gas pressure P1 in opening the purge valve 18 and anode off-gas pressure P2 when a certain time has passed, and an opening/closing time of the purge valve is corrected on the basis of the calculated purge amount. <P>COPYRIGHT: (C)2007,JPO&INPIT |
