摘要:
主要对500 W空冷型PEMFC电堆进行了电堆负载动态阶跃响应、单电池电压均一性以及电堆内部温度分布实验研究.通过变载实验,发现电堆每次变载时电压都出现过冲现象,同时同一电流下对应的温度和电压,加载过程要比卸载过程低; 单电池电压随着负载增加,波动越来越大,距离阳极排水口较远的单电池最容易发生水淹,位于电堆中部位置的NO.13～NO.21单电池电压均一性表现较好; 电堆内部温度分布不均匀,与位置有很大关系,在不同负载下,电堆底部温度要比顶部温度高.
Abstract:
The dynamic load response of the stack,the uniformity of the cell voltage,and the internal temperature distribution of the stack are performed for a 500 W air-cooled PEMFC stack.Through variable load experiments,it is found that the voltage of the stack is overshooted while load is changed.At the same time,the corresponding temperature and voltage under the same current,the loading process is lower than the unloading process.With the increase of the load,the cell voltage will fluctuate more and more.Single cells far from the anode outlet are most likely to be flooded,and the voltage uniformity of the NO.13～NO.21 cell located in the middle of the stack is performs well.The temperature distribution inside the stack is not uniform and has a large relationship with the location.Under different loads,the temperature at the bottom of the stack is higher than that at the top.
