The invention provides a system and a method for reducing air inflow during idling of a fuel cell, and the system comprises an air filter, an air compressor, an intercooler, a first throttle valve, asecond throttle valve, a humidifier and an FEMC. The first throttle valve is connected with the air compressor in parallel through a bypass pipe, the output end of the air filter is connected with theinput end of the air compressor. The output end of the air compressor is connected with the input end of the intercooler, the output end of the intercooler is connected with the input end of the humidifier, the output end of the humidifier is connected with the input end of the FEMC, and the output end of the FEMC is connected with the input end of the second throttle valve. A pipeline and a throttle valve are additionally arranged in front of an intercooler and an air compressor. Excessive air is shunted before the intercooler, so that the amount of air flowing through the intercooler is reduced, namely the air flowing through the PEMFC is reduced.

    本发明提供一种降低燃料电池怠速时空气进气量的系统及方法,包括空滤、空压机、中冷器、第一节气门、第二节气门、增湿器以及FEMC,利用旁通管辂,将第一节气门与所述空压机并联,所述空滤机的输出端连接空压机的输入端,空压机的输出端连接中冷的输入端,中冷器的输出端连接增湿器的输入端,增湿器的输出端连接FEMC的输入端,FEMC的输输出端连接第二节气门的输入端,本发明在中冷器前与空压机前增加一条管路并增加节气门,将过量的空气在中冷器前进行分流,从而降低流经中冷器的空气量,即减少流经PEMFC的空气。
