Cathode materials are critical for microbial electrolysis cell (MEC) development and its contribution to achieving a circular hydrogen economy. There are numerous reports on the progress in MEC cathode development during the past decade, but a comprehensive review on the quantitative comparisons and critical assessments of these works is lacking. This Review summarizes and analyzes the published literature on MEC cathode and catalyst development in the past decade, providing an overview of new materials examined during this time period and quantitative analyses on system performance and trends in materials development. Collected data indicate that hybrid materials have become the most popular catalyst candidate while nickel materials also attract increasing interest and exploration. However, the dilemma between higher H production rate and larger MEC volume remains and still requires more investigation of novel MEC cathode catalysts and configurations to offer a solution.
阴极材料对于微生物电解池（MEC）的发展及其对实现循环氢经济的贡献至关重要。在过去十年中，有许多关于MEC阴极发展进展的报道，但缺乏对这些工作的定量比较和批判性评估的全面综述。本综述总结并分析了过去十年中关于MEC阴极和催化剂发展的已发表文献，概述了在此期间研究的新材料，并对系统性能和材料发展趋势进行了定量分析。收集的数据表明，混合材料已成为最受欢迎的催化剂候选材料，而镍材料也吸引了越来越多的关注和探索。然而，更高的产氢速率和更大的MEC体积之间的困境仍然存在，仍需要对新型MEC阴极催化剂和配置进行更多研究以提供解决方案。
