Abstract
A control device for starting a fuel cell is provided which is capable of preventing an excessive reduction of the terminal voltage of the fuel cell. A primary precharge portion, provided with a high voltage switch and a current limiter, is disposed at the output portion of a power storage unit, and a secondary precharge portion, provided with a DC-DC chopper and a control portion, is disposed at the output side of a fuel cell. The primary precharge portion controls the output current to flow in a path via a resistor having a predetermined resistance. The secondary precharge portion controls an output current of the fuel cell based on a current command value IFCCMD for the fuel cell.
