제어부에서 차량의 시동명령을 체크하는 시작단계; 제어부에서 수소밸브를 오픈하여 연료전지에 수소를 공급하는 수소공급단계; 제어부에서 수소 공급 후 연료전지 전압의 상승여부를 체크하는 전압체크단계; 및 제어부에서 수소 공급 후 연료전지의 전압이 상승한 것으로 판단되는 경우 연료전지에 부하장치를 연결하여 연료전지의 발전전력을 소모하고, 공기밸브를 오픈하여 연료전지에 공기를 공급하며, 전력변환장치의 버스단 전압 제어를 통하여 연료전지의 전압을 일정 수준 이하로 제어하는 제1시동단계;를 포함하는 연료전지 차량의 시동 제어방법이 소개된다.

    A method for controlling startup of a fuel cell vehicle is provided. The disclosed method includes detecting generation of a startup command from a vehicle and supplying hydrogen to a fuel cell by opening a hydrogen valve. Additionally, the method includes detecting whether a fuel cell voltage has increased after supply of hydrogen, and a first startup of consuming generated electric power of the fuel cell through connection of a load device to the fuel cell, supplying air to the fuel cell through opening an air valve and adjusting the fuel cell voltage to be maintained at a predetermined level or less through adjustment of a bus stage voltage of a power converter when the controller determines that the fuel cell voltage has increased after supply of hydrogen.
