建模和仿真是研究聚合物电解质膜（PEM）燃料电池内部物理过程的成熟工具。早期的文献对主要组分的稳态输运现象给予了极大的关注，这仍然是正在进行的活动的焦点。另一方面，人们对燃料电池运行的其他方面（如瞬态性能和退化现象）的建模越来越感兴趣。由于模拟技术的发展和计算机硬件的增强，对燃料电池组件中的传输现象进行的分子和孔隙水平研究的数量也有所增加。这种方法能够比传统的宏观模型更忠实地代表重要的小尺度现象。本文综述了PEM燃料电池建模的最新活动，重点是详细的物理模型，并认为其潜在的意义。还提供了一个工业的角度来看，突出了目前使用的建模在测试和设计周期，并概述了未来的要求。
Modelling and simulation are well-established tools for investigating the physical processes inside a polymer electrolyte membrane (PEM) fuel cell. The early literature paid great attention to steady-state transport phenomena in the main components, which continues to be a focus of ongoing activities. There is, on the other hand, a growing interest in modelling other aspects of fuel cell operation, such as transient performance and degradation phenomena. There has also been a growth in the number of molecular and pore-level studies of transport phenomena in fuel cell components, enabled by developments in simulation techniques and enhancements in computer hardware. Such approaches are capable of representing important small-scale phenomena more faithfully than traditional macroscopic models. This review summarises recent activity in PEM fuel cell modelling, with a focus on detailed physical models, and considers its potential significance. An industrial perspective is also provided, highlighting the current use of modelling in the test and design cycles, and outlining future requirements.
