摘要： An air supply control method of a fuel cell controls an amount of air supplied to the fuel cell according to an output of power required to be generated by the fuel cell. The method includes steps of: monitoring a charging level of a power storage device that stores power output from the fuel cell; modifying the amount of air supplied to the fuel cell on the basis of the monitored charging level of the power storage device; and controlling an air supply system that supplies air to the fuel cell on the basis of the modified amount of air supplied.

摘要： A control method for a motor-driven vehicle is provided. The method includes calculating a correction torque of a drive motor through a difference between speeds of wheels or a variance rate of the difference between speeds of the wheels and comparing a calculated correction torque with a current required torque of the drive motor. When the calculated correction torque is greater than the current required torque, the drive motor is operated based on the current required torque. When the calculated correction torque is less than or equal to the current required torque, the drive motor is operated based on the calculated correction torque, or the required torque of the drive motor is corrected to correspond to the calculated correction torque and the drive motor is operated based on a corrected required torque of the drive motor.

摘要： A method for controlling an operation of a fuel cell of a fuel cell vehicle is provided. The method includes detecting a state of charge (SOC) of a high voltage battery and determining whether the detected SOC of the high voltage battery is within or beyond a preset range from a minimum recommended SOC to a maximum recommended SOC. Power generation of the fuel cell is performed or stopped by comparing a required current of the vehicle with a preset current value required to enter a fuel-cell stop mode in which the power generation of the fuel cell is stopped and a preset current value required to release the fuel-cell stop mode.
