摘要:

氢是碳中和能源系统的重要组成部分,为重工业和长途运输等难以脱碳的行业提供了一种可替代路径。可再生能源电解制氢是最可持续的制氢技术,为整合间歇性可再生能源提供了额外的灵活性,并可以作为季节性储能。质子交换膜(PEM)电解水技术具有电流密度高、运行压力高、电解槽体积小、整体性和灵活性好等优势,与波动性较大的风电和光伏有很好的适配性,但目前的主要挑战之一是其成本较高。本文对PEM电解水技术的成本组成及应用现状进行了总结,并详细分析了PEM电解槽中的关键材料、制备工艺及组件制造的研究进展。研究认为,通过新型的结构设计、制备策略和制造技术,可以提升贵金属催化剂的活性和利用率,减少膜厚度以降低欧姆极化,降低双极板的原料和加工成本,改善电解槽的结构设计和组装。最后提出了未来PEM电解水技术的研发方向和目标,通过材料性能的技术创新、组件制造工艺的优化、电解槽生产规模的扩大,能显著降低PEM电解水设备的成本,加速PEM制氢的规模化发展。

Abstract:

Hydrogen is an essential element for a net carbon energy system that provides an alternative to difficult sectors for deep decarbonization, including heavy industry and long-haul transport. Electrolytic hydrogen synthesized through renewables is the most sustainable technology. It offers additional flexibility to integrate intermittent renewable energy and also can be used as seasonal energy storage. High current density, high operating pressure, small electrolyzer size, good integrity, and flexibility are all benefits of proton exchange membrane (PEM) water electrolysis technology. It also has good adaptability to the high volatility of wind and PV power. However, one of the main challenges is its high cost. The cost composition and application status of PEM water electrolysis are summarized in this study, and the research progress in critical materials, preparation technology, and component manufacturing are addressed in depth. According to research, novel structure-design preparation strategies and manufacturing technology are expected to improve electrolyzer design and construction, decrease the cost of raw materials and manufacturing for bipolar plates, decrease ohmic polarization by reducing membrane thickness, and increase the activity and utilization of noble-metal catalysts. Finally, the future R&D direction and target of PEM water electrolysis are proposed. With technology innovation in material performance, optimization of component manufacturing, and an increase in electrolyzer plant scale, significantly reducing the cost of PEM water electrolysis equipment and accelerating the large-scale development of PEM hydrogen production.
