NOVELTY - The method involves calculating rate-of-change of a value of motor current requirement by a controller. A value for a supplementary air intake is calculated (S300) by multiplying the rate-of-change of the value of the motor current requirement by a gain value and the controller. A value for a final air intake is calculated (S400) by adding a value for a basic air intake and the value for the supplementary air intake by the controller. An air blower of an air intake system of a fuel cell is operated with the value for the final air intake by the controller.    USE - Method for controlling an air intake of a fuel cell vehicle. Uses include but are not limited to internal combustion engine vehicle, motor vehicle such as passenger automobile, sports utility vehicle, bus, lorry, commercial vehicle, boat, ship, and aircraft, hybrid vehicle, electric vehicle, plug-in hybrid electric vehicle, hydrogen-powered vehicle, and alternative fuel vehicle.    ADVANTAGE - The method allows a vehicle to avoid shortage of air or an excessive air supply to the fuel cell by air supply optimization, thus improving durability of the fuel cell. The method enables maintaining acceleration performance of the vehicle by improving output power ascension speed of the fuel cell by maintaining an amount of air flow preemptively.
