The occurrence of degradation and damage to a fuel cell when power supply to accessories for driving the fuel cell is stopped, is prevented. Respective collision judgment sections read in an acceleration signal output from corresponding acceleration sensors and judge if the acceleration signal is greater than a predetermined first threshold acceleration, and if the judgment result is "YES", close a hydrogen control valve. They then judge if the acceleration signal exceeds a predetermined second threshold acceleration greater than the first threshold acceleration, and if the judgment result is "YES", stop power supply from a power storage unit to an air compressor for driving the fuel cell.
