Abstract

With the development of hydrogen energy, there has been increasing attention on fuel cells and water electrolysis. Among them, the zero-gap membrane electrode assembly (MEA) serves as an important triple-phase reaction site that determines the performance and efficiency of the reaction system. The development of efficient and durable MEAs plays a crucial role in the development of hydrogen energy. Consequently, a great deal of effort has been devoted to developing ordered MEAs that can effectively increase catalyst utilization, maximize triple-phase boundaries, enhance mass transfer and improve stability. The research progress of ordered MEAs in recent advances is highlighted, involving hydrogen fuel cells and low temperature water electrolysis technology. Firstly, the fundamental scientific understanding and structural characteristics of MEAs based on one-dimensional nanostructures such as nanowires, nanotubes and nanofibers are summarized. Then, the classification, preparation and development of ordered MEAs based on three-dimensional structure are summarized. Finally, this feature article presents current challenges and proposes future research of ordered MEAs and offers potential solutions to overcome these obstacles.

电解水用有序膜电极组件的开发与应用

随着氢能的发展，燃料电池和水电解越来越受到人们的关注。其中，零间隙膜电极组件（MEA）作为重要的三相反应场所，决定着反应系统的性能和效率。开发高效耐用的 MEA 对氢能的开发起着至关重要的作用。因此，人们一直致力于开发有序 MEA，以有效提高催化剂利用率、最大限度地利用三相边界、增强传质和提高稳定性。本文重点介绍了有序 MEAs 近年来的研究进展，涉及氢燃料电池和低温水电解技术。首先，总结了基于一维纳米结构（如纳米线、纳米管和纳米纤维）的 MEAs 的基本科学认识和结构特征。然后，总结了基于三维结构的有序 MEAs 的分类、制备和发展。最后，这篇特写文章介绍了有序 MEAs 目前面临的挑战，提出了未来的研究方向，并提供了克服这些障碍的潜在解决方案。
