Abstract

Proton exchange membrane water electrolysis (PEMWE), as a promising technology for hydrogen production from renewable energy sources, has great potential for industrial application. Gas bubbles are known to influence the PEMWE cell performance significantly, but a full picture of bubble behaviors and their impacts on cell performance has been lacking. In this review, we first discuss the most recent advances toward understanding the bubble evolution and transport processes as well as the mechanisms of how bubbles impact the PEMWE. Then the state-of-the-art bubble management methods to mitigate bubble-induced performance losses are summarized. Due to the similarity between PEMWE and anion exchange membrane water electrolysis (AEMWE), we also extend related discussions for AEMWE. Lastly, we present principles of bubble management, followed by an outlook of scientific questions and suggestions for future research priorities.

PEM电解过程中气泡的演化与传输:机制、影响与管理

质子交换膜电解是一种很有前途的可再生能源制氢技术，具有很大的工业应用潜力。众所周知，气泡会显著影响PEMWE电池的性能，但对气泡行为及其对电池性能的影响还缺乏全面的了解。在这篇综述中，我们首先讨论了在理解气泡演化和传输过程以及气泡如何影响PEMWE的机制方面的最新进展。然后总结了目前最先进的气泡管理方法，以减轻气泡引起的性能损失。由于PEMWE与阴离子交换膜电解(AEMWE)的相似性，我们也对AEMWE进行了相关的讨论。最后，我们提出了气泡管理的原则，然后展望了科学问题和对未来研究重点的建议。

期刊介绍： Progress in Energy and Combustion Science (PECS) publishes review articles covering all aspects of energy and combustion science. These articles offer a comprehensive, in-depth overview, evaluation, and discussion of specific topics. Given the importance of climate change and energy conservation, efficient combustion of fossil fuels and the development of sustainable energy systems are emphasized. Environmental protection requires limiting pollutants, including greenhouse gases, emitted from combustion and other energy-intensive systems. Additionally, combustion plays a vital role in process technology and materials science. PECS features articles authored by internationally recognized experts in combustion, flames, fuel science and technology, and sustainable energy solutions. Each volume includes specially commissioned review articles providing orderly and concise surveys and scientific discussions on various aspects of combustion and energy. While not overly lengthy, these articles allow authors to thoroughly and comprehensively explore their subjects. They serve as valuable resources for researchers seeking knowledge beyond their own fields and for students and engineers in government and industrial research seeking comprehensive reviews and practical solutions.
