The behavior of proton exchange membrane fuel cells (PEMFCs) strongly depends on the operational temperatures. In mobile applications, for instance in fuel cell electric vehicles, PEMFC stacks are often subjected to temperatures as low as −20 °C, especially during cold start periods, and to temperatures up to 120 °C during regular operation. Therefore, it is important to understand the impact of temperature on the performance and degradation of hydrogen fuel cells to ensure a stable system operation. To get a comprehensive understanding of the temperature effects in PEMFCs, this manuscript addresses and summarizes in‐ situ and ex‐ situ investigations of fuel cells operated at different temperatures. Initially, different measurement techniques for thermal monitoring are presented. Afterwards, the temperature effects related to the degradation and performance of main membrane electrode assembly components, namely gas diffusion layers, proton exchange membranes and catalyst layers, are analyzed.

聚合物电解质膜燃料电池的温度效应

质子交换膜燃料电池（PEMFC）的行为在很大程度上取决于工作温度。在移动应用中，例如在燃料电池电动汽车中，PEMFC电池组通常会承受低至-20°C的温度（尤其是在冷启动期间），而在常规操作期间会承受高达120°C的温度。因此，重要的是要了解温度对氢燃料电池性能和退化的影响，以确保系统稳定运行。要获得PEMFC中的温度影响，该手稿地址的全面了解和总结在- 原位和EX- 原位在不同温度下运行的燃料电池的研究。最初，介绍了用于热监控的不同测量技术。然后，分析了与主要膜电极组件的降解和性能有关的温度效应，这些主要膜电极组件是气体扩散层，质子交换膜和催化剂层。
