PROBLEM TO BE SOLVED: To minimize a delay in power supply to a load and effectively utilize charging power in a battery. SOLUTION: In a control method for a DC/DC converter 7 for a heavy current, which permits power generated by a fuel cell stack 1 to be supplied to the fuel cell stack 1 and a compressor motor 3, and is stored in a secondary cell 8, signals indicating command power quantity is inputted from a controller 14, load power quantity supplied to the secondary cell 8 or a drive motor 11 is computed, operational power quantity outputted from the DC/DC converter 7 for a heavy current is computed, a power quantity difference between load power quantities is computed, and operational power quantity to be outputted from the DC/DC converter 7 for a heavy current for the next time is determined based on the power quantity equivalent to the power quantity difference for supplying power to the drive motor 11 or to the secondary cell 8. |
