The disclosure provides cathode inlet humidity sensing with a universal exhaust oxygen sensor. A fuel cell system includes a stack of proton exchange membrane (PEM) fuel cells defining a body, the body including a coolant inlet and coolant outlet, a cathode inlet and cathode outlet corresponding to a cathode, an anode inlet and an anode outlet corresponding to an anode. The fuel cell system also includes a cathode humidifier fluidly connected to the cathode inlet to provide a humidified inlet stream to the cathode inlet, a universal exhaust oxygen sensor (UEGO) positioned upstream of the cathode inlet and downstream of the cathode humidifier, and configured to measure oxygen content of the humidified inlet stream, and a controller connected to the cathode humidifier and the oxygen sensor and the UEGO snesor and configured to operate the cathode humidifier based on the oxygen content of the humidified inlet stream.

    本公开提供了“利用通用排气氧传感器的阴极入口湿度感测”。一种燃料电池系统,包括质子交换膜(PEM)燃料电池堆,所述PEM燃料电池堆限定主体,所述主体包括冷却剂入口和冷却剂出口、对应于阴极的阴极入口和阴极出口、对应于阳极的阳极入口和阳极出口。所述燃料电池系统还包括:阴极加湿器,所述阴极加湿器流体地连接到所述阴极入口以向所述阴极入口提供经加湿的入口流;通用排气氧(UEGO)传感器,所述UEGO传感器定位在所述阴极入口的上游且在所述阴极加湿器的下游,并且被配置为测量所述经加湿的入口流的氧含量;以及控制器,所述控制器连接到所述阴极加湿器和所述UEGO传感器并且被配置为基于所述经加湿的入口流的所述氧含量操作所述阴极加湿器。
