Abstract:
1. A fuel cell system in which an electric storage device and a fuel cell are connected in parallel with each other via a DC/DC converter, the fuel cell system comprising: a device configured to stop the DC/DC converter when an abnormality occurs in the DC/DC converter; a device configured to make an attempt to recover the DC/DC converter to a normal state after the DC/DC converter is stopped; a device configured to generate drive power in at least the fuel cell until the DC/DC converter recovers to the normal state; a device configured to set a limit on a value of power capable of passing through the DC/DC converter, at the latest, by the time the DC/DC converter starts to recover to the normal state; and a device configured to set an upper limit of power which can be generated in the fuel cell system when the DC/DC converter recovers to the normal state to a value lower than an upper limit of power generated before the abnormality occurs.
