摘要： An emergency start device of a fuel cell vehicle having a motor as a driving source is provided and includes a fuel cell that supplies power to a motor and an air blower that supplies air to the fuel cell. A high voltage battery supplies power to the air blower and a direct current (DC) converter increases an output of the high voltage battery to transfer the output to the air blower. In addition, a first switch transfers or intercepts an output of the high voltage battery to the air blower. By directly transferring a voltage of the high voltage battery to the air blower, the fuel cell is driven, when the DC converter fails while driving by the high voltage battery.

摘要： A fuel cell power plant keeps track, such as with a fuel-off timer (41), of the extent to which shutdown of the fuel cell power plant has occurred, in case the fuel cell power plant is quickly commanded to resume full operation. In one embodiment, if the fuel-off timer has not timed out at the time that the fuel cell power plant is ordered to resume full operation, a fuel-on timer is set (51) equal to the value of the fuel-off timer when the fuel cell power plant is ordered to resume full operation. Then, the fuel cell power plant is refueled (22), in a duration of time related to the setting of the fuel-off timer, rather than doing a full fuel purge.

摘要： Disclosed is a system and method for controlling a fuel cell system. More specifically, a fuel cell demand current is calculated based on a driver demand current calculated from a driver demand torque. Then a target flow rate-1 of air to be supplied to a fuel cell stack is calculated based on the fuel cell demand current and a target stoichiometric ratio (SR) of air. The target flow rate-1 is then compensated for using the target SR, an RPM command value of an air blower is calculated based on a compensated target flow rate-2 and the amount of air currently measured. The operation of the air blower is subsequently controlled based on the calculated RPM command value.
