摘要
为了研究燃料电池汽车运行工况对燃料电池老化的影响,提出了一种质子交换膜燃料电池(PEMFC)老化机理模型,并与经试验验证的PEMFC多物理场模型耦合,建立了能预测燃料电池性能衰退的老化模拟器。利用该老化模拟器,模拟研究了在城市公交车运行基准循环工况和所设计的加速老化循环工况下燃料电池性能衰减情况。结果表明,所建立的老化模拟器能预测公交车燃料电池运行工况对燃料电池老化的影响,燃料电池在所设计的加速老化循环工况下的电压衰退速率约为基准循环工况的2倍。
In order to study the effect of fuel cell vehicle operating conditions on fuel cell aging,an aging mechanism model of proton exchange membrane fuel cell(PEMFC)was proposed.Coupled with the validated PEMFC multi-physics model,an aging simulator was established to predict the aging of fuel cell performance.Using the proposed aging simulator,the performance degradations of fuel cell under the baseline operating cycle for fuel cell city buses and the designed accelerated aging conditions were simulated.The results show that the aging simulator can predict the impact of fuel cell bus operating cycles on fuel cell aging,and the degradation rate of fuel cells under the designed aging acceleration cycle is about 2 times that of the baseline operating cycle.
