This project aims to develop robust, efficient porous hybrid hydrogen electrodes for electrochemical hydrogen production in anion exchange membrane water electrolyser. anion exchange membrane water electrolyser powered by renewable energy has emerged as a key avenue towards clean hydrogen with zero carbon footprint. However, the electrochemical turnover on the hydrogen electrode has been significantly hindered by the sluggish reaction kinetics in alkaline solution. The project is expected to generate cost-effective hydrogen electrodes for hydrogen electrolyzers, advanced knowledge in the electrode material engineering, electrochemical reaction mechanistic insights, and eventually promoted development of disruptive electrolysis technology.

该项目旨在开发坚固、高效的多孔混合氢电极，用于阴离子交换膜水电解槽中的电化学制氢。由可再生能源驱动的阴离子交换膜水电解槽已成为实现零碳足迹的清洁氢的关键途径。然而，碱性溶液中缓慢的反应动力学严重阻碍了氢电极上的电化学转换。该项目预计将为氢电解槽生产具有成本效益的氢电极、电极材料工程的先进知识、电化学反应机理的见解，并最终促进颠覆性电解技术的发展。
