Abstract
A fuel cell vehicle includes a fuel cell stack including a cathode flow field and an anode flow field, an atmospheric air pressure acquisition unit for obtaining pressure of atmospheric air, and a pump for sucking the atmospheric air and supplying an oxygen-containing gas to the cathode flow field through a supply channel. In the case where the temperature is predicted to be below freezing temperature after the time of stopping operation of the fuel cell stack, a scavenging period for the time of stopping operation is set based on the atmospheric air pressure, in order to perform scavenging of the cathode flow field by the oxygen-containing gas in a manner that the cathode flow field is placed in a predetermined humid state.
