A device and method for controlling start-up of a fuel cell vehicle are provided and include a table in which a time-difference between a hydrogen supply initiating time-point and an air supply initiating time-point is recorded for each cooling water temperature at a fuel cell stack outlet. The air supply initiating time-point is adjusted based on the table during the start-up of the fuel cell vehicle to prevent a cell voltage deviation and a cell reverse voltage of the fuel cell stack. A temperature sensor measures a cooling water temperature of a fuel cell stack and a controller adjusts the air supply initiating time-point based on the cooling water temperature of the fuel cell stack during start-up of a fuel cell vehicle.
提供了控制燃料电池车辆的启动的装置和方法,该装置和方法包括图表,在该图表中记录针对燃料电池堆的出口处的每个冷却水温度的氢气供应开始时间点与空气供应开始时间点之间的时间差。在燃料电池车辆的启动期间,基于图表调整空气供应开始时间点,以防止燃料电池堆的电池电压偏差和电池反向电压。在燃料电池车辆的启动期间,温度传感器测量燃料电池堆的冷却水温度,并且控制器基于燃料电池堆的冷却水温度调整空气供应开始时间点。
