Enhancing the endurance and efficiency of polymer electrolyte membrane fuel cells (PEMFCs) requires efficient thermal management. This comprehensive review examines the primary cooling techniques employed in PEMFC systems, concentrating on techniques for air and liquid cooling. Liquid cooling, which circulates a coolant through channels adjacent to the ability of the fuel cell stack to maintain ideal operating temperatures, is highlighted and significantly reduces temperature variations, thereby improving overall efficiency and lifespan. In contrast, air cooling, while simpler and more cost-effective, is less effective in high-power applications due to its reliance on ambient air for heat dissipation. The review also discusses advancements in thermal management strategies, including innovative designs for heat exchangers and the integration of thermal resistance networks, which enhance heat dissipation efficiency. Furthermore, the paper underscores the importance of developing durable materials to address catalyst and membrane degradation, and it explores the potential for integrating PEMFCs using renewable energy sources to encourage environmentally friendly transportation solutions. By identifying current challenges and proposing future research directions, this review aims to support the continuous creation of effective and reliable PEMFC technologies.
提高聚合物电解质膜燃料电池（PEMFC）的耐久性和效率需要高效的热管理。这篇综述全面考察了PEMFC系统中采用的主要冷却技术，重点关注空气冷却和液体冷却技术。突出了液体冷却，即让冷却剂在与燃料电池堆相邻的通道中循环，这有助于燃料电池堆维持理想的工作温度，能显著减少温度变化，从而提高整体效率和使用寿命。相比之下，空气冷却虽然更简单且成本效益更高，但在高功率应用中效果较差，因为它依赖环境空气进行散热。该综述还讨论了热管理策略的进展，包括热交换器的创新设计和热阻网络的集成，这些都提高了散热效率。此外，本文强调了开发耐用材料以解决催化剂和膜降解问题的重要性，并探讨了整合使用可再生能源的PEMFC以推动环保交通解决方案的潜力。通过识别当前的挑战并提出未来的研究方向，本综述旨在支持持续创造有效且可靠的PEMFC技术。
