A fuel cell starting control method is introduced. The method comprises the steps of: calculating available power of a high voltage battery when a fuel cell start is requested; controlling driving of an air compressor based on the calculated available power of the high voltage battery; and charging a low voltage battery using the power of the high voltage battery after completing the drive control of the air compressor. According to the present invention, a target rotational speed of the air compressor is varied to minimize the start failure of the fuel cell.
