分子电催化研究领域包括广泛的新兴技术，这些技术利用分子催化剂来催化燃料电池装置内的阳极和/或阴极反应，并且在过去10年中得到了很大的发展。尽管绝大多数燃料电池使用贵金属作为催化剂，但最近已经开发了几种基于分子催化剂的系统。这里的重点是将分子催化剂整合到燃料电池装置中，这是有背景的，在这里被命名为“基于燃料电池的分子型催化剂”。后者利用各种各样的化合物，如有机金属化合物和有机或生物启发的化合物，以收获化学能来产生电流。在这里，讨论了在燃料电池装置中转换化学能的所有分子催化剂的最新技术水平，并提出了一种新的分类系统，以说明分子催化剂如何融入燃料电池的广泛领域。总结了分子催化剂在使用不同燃料的系统中的当前性能，最后，首次提出了使用独特分子催化剂的燃料电池可实现的功率输出。
The field of molecular electrocatalysis research includes a wide range of emerging technologies that utilize molecular catalysts to catalyze anodic and/or cathodic reactions within a fuel‐cell setup, and has developed greatly in the last 10 years. Although the vast majority of fuel cells utilize noble metals as catalysts, several systems have been recently developed that are based on molecular catalysts. The focus here is on the integration of molecular catalysts in a fuel‐cell setup, which is contextualized, and which is named as “fuel‐cell‐based molecular‐type catalysts” here. The latter utilize a wide variety of chemical compounds, such as organometallics and organic or bioinspired compounds, to harvest chemical energy to generate current. Here, the state‐of‐the‐art for all molecular catalysts that convert chemical energy in a fuel‐cell setup is discussed and a novel classification system is presented to illustrate how molecular catalysts integrate into the broad field of fuel cells. The current performance of molecular catalysts in systems that use different fuels is summarized, and finally, for the first time, the achievable power outputs of fuel cells using uniquely molecular catalysts are presented.
