摘　　要：燃料电池做为汽车动力源时,应能够在多变环境和不同工况下保持高效、稳定的工作状态。燃料电池在不同工况下,其运行参数对燃料电池本身性能的影响是不同的。为给燃料电池提供合适的工作条件,确保燃料电池在高效区运行。通过对高压质子交换膜燃料电池的正交试验研究,分析流量、压力和温度等运行参数对高压燃料电池性能的影响,得到如下结论:空气流量对燃料电池性能的影响较小,随着电流的增加,影响有所增加;空气压力的影响略大,并且在小电流时,这种影响比较显著;氢气压力(压力差)的影响始终很小,几乎可以认为没有影响;燃料电池工作温度对燃料电池性能的影响仍然十分大,并且随着温度的升高,其影响越来越大;随着电流的加大,燃料电池温度的影响也逐渐增大,在高电流状态下,几乎是唯一重要的影响因素。As the power unit of automobile, fuel cell system should be stable and highly efficient under different load conditions in variable environment. Under different load conditions, operation parameters of fuel cell system have different impact on its performance. Correct operation parameters should be employed to make sure fuel cell system operates in high-efficiency zone. Orthogonal tests are employed to analyze the effect of operation parameters, such as flow rate, pressure, temperature, on the performance of the high-pressure fuel cell system. Some conclusions are derived from the tests. Air flow rate has less effect on the performance of fuel cell system, however, with the increase of current, the effect increases slightly. Air pressure has greater impact on the performance of fuel cell system, and such impact is remarkable when the current is low. Hydrogen pressure always has little effect. Operation temperature has very great impact on the performance of fuel cell system, and with the rise of temperature, its impact is more and more great. With the increase of current, the effect of temperature is also gradually increasing, and it becomes the only significant affecting factor when the current is high.
