FUEL CELL SYSTEM

摘要

Provided is a fuel cell system which can perform sufficient scavenging during a current system operation even if scavenging during the previous system stop has been insufficient. When a control device (7) detects that a system start command is inputted and a low temperature mode flag (80) is turned ON, the control device (7) compares a measurement impedance Im during the previous system stop stored in a measurement impedance memory (91) to a low temperature start target impedance It stored in a reference impedance memory (92) so as to judge whether the scavenging process performed during the previous system stop has been insufficient. When the control device (7) judges that the scavenging process performed during the previous system stop has been insufficient, a rapid warm-up operation is executed during the current system operation so as to rapidly increase the temperature.
