A fuel cell system includes: an AC impedance measuring unit (92) which measures an AC impedance of a fuel cell upon scavenging start and measures an AC impedance of a fuel cell when a predetermined time has elapsed from the scavenging start; a scavenging execution time estimation unit (94) which estimates the AC impedance measured at scavenging start moment, the AC impedance measured at the moment when the predetermined time has elapsed from the scavenging start moment, and the scavenging execution time based on the predetermined time; and a limit unit (95) which limits the scavenging execution time to a maximum scavenging time if the scavenging execution time exceeds the maximum scavenging time. |
