Title: FUEL CELL SYSTEM, AND ELECTRIC VEHICLE EQUIPPED WITH THE FUEL CELL SYSTEM
Abstract:
A fuel cell system starts a fuel cell by setting the voltage supplied to a secondary cell from a voltage transformer at an open-circuit voltage of the fuel cell, and raising the voltage of the fuel cell from a starting voltage to the open-circuit voltage, in the case where the secondary cell is expected to be overcharged if the secondary cell receives electric power. In the case where the secondary cell is not expected to be overcharged if the secondary cell receives electric power, the system starts the fuel cell by setting the voltage supplied from the voltage transformer at a high-potential-avoiding voltage that is lower than the open-circuit voltage of the fuel cell at or after the elapse of a predetermined time following the output of a command to close an FC relay, and raising the voltage of the fuel cell from the starting voltage to the high-potential-avoiding voltage.
