Water electrolyzers powered by renewable energy are emerging as clean and sustainable technology for producing hydrogen without carbon emissions. Specifically, anion exchange membrane (AEM) electrolyzers utilizing non-platinum group metal (non-PGM) catalysts have garnered attention as a cost-effective method for hydrogen production, especially when integrated with solar cells. Nonetheless, the progress of such integrated systems is hindered by inadequate water electrolysis efficiency, primarily caused by poor oxygen evolution reaction (OER) electrodes. To address this issue, a NiFeCo─OOH has developed as an OER electrocatalyst and successfully demonstrated its efficacy in an AEM electrolyzer, which is powered by renewable electricity and integrated with a silicon solar cell.
由可再生能源驱动的水电解槽正在成为一种清洁且可持续的技术，用于生产无碳排放的氢气。具体而言，利用非铂族金属（non-PGM）催化剂的阴离子交换膜（AEM）电解槽作为一种具有成本效益的制氢方法受到了关注，尤其是与太阳能电池集成时。尽管如此，这种集成系统的进展受到水电解效率不足的阻碍，这主要是由析氧反应（OER）电极性能不佳导致的。为了解决这个问题，一种NiFeCo─OOH已被开发作为OER电催化剂，并成功在由可再生电力驱动并与硅太阳能电池集成的AEM电解槽中证明了其有效性。
