燃料电池耐久试验循环工况对比

Comparison of duty cycles for fuel cell durability bench tests

介绍目前国内外几种主要的车用燃料电池堆耐久性台架试验循环工况及评价方法,对各种循环工况的构成要素、适用范围等方面进行了对比分析,得出美国能源部、同济大学、清华大学循环工况具有包含易造成车用燃料电池堆衰减的4个典型工况,HYZEM工况具有电流连续加载等工况的各自特点。

Several duty cycles and their evaluation methods which proposed by domestic and foreign departments for vehicular fuel cell durability bench tests were introduced. The comparative analysis was done on these duty cycles in composition factors, application range and other aspects. Their features were found for providing guidance for choosing proper duty cycles fro＇ vehicular fuel cell durability bench tests,such as U. S. department of energy cycle,Tongji university cycle and Tsinghua university cycle,flint typical working conditions which could easily lead to the degradation of vehicular fuel cell stack. Current loading in the hybrid technology approaching efficient zero emission mobility driving cycle was continuous.
