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 (23a, 24a, 25a and 26a) read in an acceleration signal (G) output from corresponding acceleration sensors (23R, 24L, 25F and 26c) and judge if the acceleration signal (G) is greater than a predetermined first threshold acceleration (G1), and if the judgment result is "YES", close a hydrogen control valve (20). They then judge if the acceleration signal (G) exceeds a predetermined second threshold acceleration (G2) greater than the first threshold acceleration (G1), and if the judgment result is "YES", stop power supply from a power storage unit (12) to an air compressor (17) for driving the fuel cell (1). <IMAGE> |
