NOVELTY - The method involves calculating (S130) a speed of an acceleration pedal by a controller. The preset output order value of the fuel cell stack or the specific output order value of the fuel cell stack which is less than the preset output order value is set (S230) by the controller, in accordance with the calculated speed. The amount of air flow to be supplied to the fuel cell stack is controlled (S310,S320) by the controller based on the set preset output order value or the specific output order value. The preset output order value corresponds to an output value requested by a driver.    USE - Method for supercharging fuel cell in vehicle. Uses include but are not limited to motor vehicle such as passenger automobile e.g. sports utility vehicle, bus, truck, various commercial vehicles, watercraft e.g. boat and ship, aircraft, electric vehicle, plug-in hybrid electric vehicle, hydrogen-powered vehicle, and both gasoline-powered and electric-powered hybrid vehicles.    ADVANTAGE - The power is to be output within a range by adding an available output of the battery to the output of the fuel cell stack corresponding to the amount of currently supplied air flow, instead of increasing the amount of air flow, when the torque value requested by the driver is greater than the torque value corresponding to the total available output value while a driver is driving at a constant speed, so as to prevent the energy loss and the performance deterioration of the fuel cell stack which is occurred by excessively increasing the amount of air flow to improve fuel efficiency. The amount of air flow is increased instantly to generate the requested torque by the driver to improve acceleration when the driver accelerates. The air supercharging which is occurred by calculating the electric current requested to the fuel cell stack through the torque requested by a driver and the performance deterioration of the fuel cell stack which is caused from the drying-out inside can be prevented, and the performance deterioration of acceleration is avoided, so as to improve the fuel efficiency and acceleration performance.
