<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which carries out a sufficient scavenging in the system operation this time even if a sufficient scavenging is not performed at the system shut-down of the last time. <P>SOLUTION: When a control device 7 detects that a starting command of the system is inputted and a low-temperature mode flag 80 is switched on, the control device 7 compares the measured impedance Im at the time of the last system shut-down stored in a measured impedance memory 91 and the low-temperature starting target impedance It stored in a reference impedance memory 92, and determines whether a scavenging treatment carried out at the last system shut-down is insufficient. When the control device 7 determines that the scavenging treatment was insufficient, the control device 7 promptly increases the temperature by performing a rapid warm-up operation during the system operation this time. <P>COPYRIGHT: (C)2009,JPO&INPIT |
