| 摘 要： | 质子交换膜燃料电池(PEMFC)的效率受燃料电池设计和操作条件等多种因素的影响.文中建立了能够计算PEMFC效率的单电池稳态模型,模型预测的极化曲线与实验结果吻合良好.利用该模型研究了电池工作温度和工作压力对电池效率的影响.计算结果表明,在电池工作温度范围内,提高电池工作温度,有利于提高电池效率,高电流密度电池效率增幅要大;提高阴极和阳极工作压力均有利于电池效率提高,但阴极的工作压力增加对提高电池效率作用明显.

| Abstract: | Efficiency of proton exchange membrane fuel cell (PEMFC) stack is affected by many factors,such as stack design and operating conditions. In this paper,a steady-state model of proton exchange membrane fuel cell (PEMFC) was built to analyze the PEMFC efficiency. The polarization curve predicated by the model agreed well with the experimental results. Using the PEMFC steady-state model,the effects of cell temperature and reacting pressures on cell efficiency were numerically investigated. The simulation resul... |
