Membrane electrolyzers enable the production of high-purity H₂ from pure water. There is growing interest in developing this technology to operate in impure water. While proton-exchange-membrane (PEM) electrolyzers are the current industry leaders, anion-exchange-membrane (AEM) electrolyzers might be better suited for impure-water operation with further development. Here, the technical barriers to developing AEM electrolyzers for impure-water splitting are discussed. We highlight progress in the field and present possible research approaches to advance the field.

用于不纯水分解的膜电解槽

膜电解槽可以从纯水生产高纯度H ₂。开发这种在不纯水中运行的技术的兴趣日益浓厚。尽管质子交换膜（PEM）电解器是当前的行业领导者，但随着进一步的发展，阴离子交换膜（AEM）电解器可能更适合于不纯水操作。在此，讨论了开发用于不纯水分解的AEM电解槽的技术障碍。我们重点介绍该领域的进展，并提出可能的研究方法以促进该领域的发展。
