零间隙碱性电解槽是通过生产和分配氢气实现廉价高效可再生能源储存的关键。零间隙设计，多孔电极仅由气体分离器分隔，使碱性电解的独特优势与目前仅与更昂贵的PEM装置相关的高效率相结合。这篇综述涵盖了碱性电解的基础知识，并提供了采用零间隙电池设计优于传统安排的详细描述。比较了目前研究中不同类型的零间隙电池设计，并介绍了最近的发展。最后，对零间隙碱性电解的研究现状进行了讨论，并指出了今后的研究方向。零间隙碱性电解将允许多余的可再生能源以绿色和环保的方式储存、运输和按需使用，因为当氢燃烧或进入燃料电池时，它只产生水和能量。
Zero gap alkaline electrolysers hold the key to cheap and efficient renewable energy storage via the production and distribution of hydrogen gas. A zero gap design, where porous electrodes are spacially separated only by the gas separator, allows the unique benefits of alkaline electrolysis to be combined with the high efficiencies currently only associated with the more expensive PEM set-up. This review covers the basics of alkaline electrolysis, and provides a detailed description of the advantages of employing a zero gap cell design over the traditional arrangement. A comparison with different types of zero gap cell designs currently seen in research is made, and a description of recent developments is presented. Finally, the current state of research into zero gap alkaline electrolysis is discussed, and pathways for future research identified. Zero gap alkaline electrolysis will allow excess renewable energy to be stored, transported and used on demand in a green and environmentally friendly manner as when the hydrogen is burnt or passed into a fuel cell it produces only water and energy.
