The invention discloses a fuel cell system and a low-temperature idle speed control method. The fuel cell system comprises an air compressor, a fuel cell stack, a first stop valve, a gas adjusting system, a parameter detection system and a controller, when the vehicle is in a low-temperature idling state, the controller is used for controlling the gas adjusting system and the first stop valve to work according to the electric quantity, obtained by the parameter detection system, of the battery system and the temperature, obtained by the parameter detection system, of the fuel cell stack. Gas output from the air compressor selectively enters the fuel cell stack gas input end and/or the fuel cell stack shell gas input end. The fuel cell system enters different working states according to the temperature of the fuel cell stack and/or the electric quantity of the cell system, performance degradation caused by too high single voltage when the fuel cell works at low current can be reduced, and it can be guaranteed that the fuel cell enters the normal working state as soon as possible in the idling state by keeping the temperature of the fuel cell stack.

    本发明公开了一种燃料电池系统及低温怠速控制方法,所述燃料电池系统包括:空压机、燃料电池堆、第一截止阀、气体调节系统、参数检测系统、控制器;其中,当所述车辆在低温怠速状态下,所述控制器用于根据自所述参数检测系统所获取的所述电池系统的电量、燃料电池堆的温度来控制所述气体调节系统以及第一截止阀工作,以使自空压机输出的气体选择性进入所述燃料电池堆气体输入端和/或燃料电池堆壳体气体输入端。本发明的燃料电池系统根据燃料电池堆温度和/或电池系统电量进入不同工作状态,可降低燃料电池在低电流工作时因单体电压过高引起的性能衰减,并且通过保持燃料电池堆温度可保证燃料电池在怠速状态尽快进入正常工作状态。
