Abstract
A fuel cell vehicle according to the present disclosure includes an insulation voltage detector provided in a coolant circuit; and an ECU having a storage unit that stores an insulation voltage value detected by the insulation voltage detector. The ECU determines a coolant leak when the insulation voltage value detected by the insulation voltage detector is larger than the insulation voltage value that is obtained when an ignition was turned off a last time, the s insulation voltage values obtained when the ignition was turned off the last time being stored in the storage unit.
