PROBLEM TO BE SOLVED: To provide a method for controlling startup of a fuel cell vehicle, capable of reducing a starting preparation period through a rapid temperature increase of a fuel cell during a cold start.SOLUTION: A method for controlling startup of a fuel cell vehicle according to the present invention is a method for controlling startup of a fuel cell vehicle that includes a fuel cell, a motor, and a high-voltage battery which are connected to each other by a main bus. The method includes: a starting preparation step in which a controller starts control to supply hydrogen and air to the fuel cell; a voltage preparation step in which the controller sets a control voltage on a main bus end side of a converter to a predetermined lowest control voltage, the converter being disposed between a main bus end and the high-voltage battery; and a main controlling step in which the controller compares an output voltage of a main bus end side of the fuel cell and the control voltage of the main bus end side of the converter to adjust an amount of air supply to the fuel cell in accordance with comparison results.SELECTED DRAWING: Figure 4
