Abstract
A power supply management control unit 14 has a target output current calculator 50 including a correction processor 52 which compares an upper-limit output current (Ifc_LMT) of a fuel cell with a requested output current (Ifc_CAL) calculated by requested output current calculator 42. When the requested output current (Ifc_CAL) exceeds the upper-limit output current (Ifc_LMT), limiting the output current of the fuel cell, the correction processor 52 corrects a target output current (Ifc_CMD) to be equal to a current which is calculated by applying an open voltage (Vcap_o) of a capacitor to a map (Ifc/Vfc map) representing the correlation between an output current and an output voltage of the fuel cell. After the limitation of the out-put current of the fuel cell is canceled, the correction processor 52 keeps correcting the target output current (Ifc_CMD) until the open voltage (Vcap_o) of the capacitor becomes equal to or greater than the output voltage of the fuel cell.
