针对质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)的性能主要受到物理参数影响的问题,通过FLUENT软件建立燃料电池动力学模型,以对物理参数进行研究,得到了直行多流道单体质子交换膜燃料电池的极化曲线并对输出性能进行对比。结果表明:升高工作温度、升高运行压力以及降低质子交换膜厚度均有助于提高燃料电池输出电压,改善燃料电池的性能。研究结论将为PEMFC的设计和实际应用操作提供参考。

Effects of different parameters on the output characteristics of proton exchange membrane fuel cell

In view that the performance of Proton Exchange Membrane Fuel Cell(PEMFC)is mainly affected by physical parameters,the fuel cell dynamics model was established through FLUENT software for physical parameters research.The polarization curves of the single proton exchange membrane fuel cell with straight multi-channels were obtained and its output performance was compared.The results show that increasing operating temperature and pressure could be capable of raising the output voltage,meanwhile the decrease in thickness of the proton exchange membrane could enhance the fule cell performance.These findings will provide references for the design and practical application of PEMFC.
