| 摘 要： | 质子交换膜燃料电池内部水对交换膜的温度分布有着极为重要的影响,从而对燃料电池性能有着重大意义。以交指型结构的质子交换膜燃料电池在工作电压为0.5 V对应的工作电流密度下为例,分析研究了阴阳极不同加湿程度对膜温差的影响以及阴阳两极加湿对电流密度和膜的温度的影响的比较。数据表明,阴阳极的加湿对于膜的温差有很大的影响,且在较低加湿条件下阳极比阴极加湿更能改善电池的性能和膜的润湿程度。

| Abstract: | Proton exchange membrane fuel cell membrane exchange within the water temperature has a great influence on the distribution and thus fuel cell performance is of great significance.In this paper,the interdigitated channel of proton exchange membrane fuel cell voltage of 0.5 V corresponded to an operating current of a large case.The impacts of temperature on the membrane on the different cathode and anode humidification were analyzed.And the influences between cathode and anode were compared.The data show that the anode and cathode humidification temperature for the film has a great influence on the temperature of membrane and in lower humidifying conditions,and the anode humidifying can improve the battery’s performance and membrane wetting degree more than cathode. |
