摘要： PROBLEM TO BE SOLVED: To secure a brake force for deceleration while maintaining a preferable state for a fuel cell in a power system which is equipped with the fuel cell and performs regeneration at deceleration.
SOLUTION: When all the regenerated power of a driving motor can be stored in a secondary battery, a hydrogen pump is operated by a low output mode (S104). When all the regenerated power can not be stored in the secondary battery and in the case, if the hydrogen pump is driven by a high output mode, the sum of chargeable power to the secondary battery and the consumption power by the hydrogen pump exceeds the regenerated power of the driving motor (S108), the hydrogen pump is driven by the high output mode. Then, the target charging power Pb of the secondary battery is made as a power which is obtained by subtracting a power Ph consumed excessively by the accelerated speed of the hydrogen pump from the regenerated power Prg1. A part of a power Ph of the power Prg1 generated by the driving motor is supplied to the hydrogen pump and consumed by the hydrogen pump.
