摘要:
质子交换膜水电解（PEMWE）因其高电解效率、快速动态响应和高纯度氢气产出，被认为是最具潜力的可再生能源制氢技术之一。然而，PEMWE 的商业化推广仍受限于高成本和关键材料的性能优化需求。其中，多孔传输层（PTL）作为电解槽中的核心组件，其结构优化对提升电解槽效率和耐久性至关重要。本文系统综述了PTL的设计、制备与性能优化策略，旨在为高性能PTL的开发提供理论支持与技术参考。文章描述了PTL的主要制备工艺。探讨了PTL的结构参数（孔隙率、孔径分布、厚度）对导电性、流体渗透性及气泡传输的影响机制。进一步分析了PTL/催化剂层（CL）界面优化的必要性，微孔层（MPL）的引入是优化了PTL/CL界面的重要途径，可以提升三相界面接触面积，从而提高催化剂利用率。最后，总结并展望了未来研究方向，包括PTL涂层工艺的优化及降本，开发成本梯度微孔结构及复合结构等。本文为PEM电解水技术的高效化与低成本化提供了重要理论支撑。
Abstract:
Proton exchange membrane water electrolysis (PEMWE) is regarded as one of the most promising technologies for renewable energy-based hydrogen production due to its high efficiency, rapid dynamic response, and high-purity hydrogen output. However, the commercialization of PEMWE remains constrained by high costs and the need for performance optimization of critical materials. Among these, the porous transport layer (PTL), a core component in electrolyzers, plays a pivotal role in enhancing electrolyzer efficiency and durability through structural optimization. This review systematically examines the design, fabrication, and performance optimization strategies of PTLs, aiming to provide theoretical support and technical references for the development of high-performance PTLs. The article details the primary fabrication processes for PTLs and compares the characteristics of titanium powder-sintered PTLs, titanium fiber-sintered PTLs, and composite-structured PTLs. The influence of structural parameters—such as porosity, pore size distribution, and thickness—on conductivity, fluid permeability, and bubble transport mechanisms is thoroughly explored. Furthermore, the necessity of optimizing the PTL/catalyst layer (CL) interface is emphasized, with the introduction of a microporous layer (MPL) highlighted as a critical approach to enhance the triple-phase contact area and improve catalyst utilization. Finally, future research directions are summarized, including the optimization and cost reduction of PTL coating processes, the development of gradient microporous structures, and composite architectures. This work provides significant theoretical insights to advance the efficiency and cost-effectiveness of PEMWE technology.
