摘要

本文以零间隙结构的高电流密度和稳定性碱性电解水制氢为主题,对近年来的研究进展进行总结。依次对催化剂、电极、隔膜的催化活性、导电性、亲水性和孔结构等参数进行讨论,提出面向工业化应用的高电流密度碱性电解水制氢的影响机制与优化策略。综合研究结果,电极孔径大小对提升气泡传输和催化剂活性呈现出完全相反的作用机制、隔膜亲水性优化有助于欧姆阻抗的大幅降低。最后从电解极化原理出发,对高性能碱性电解制氢技术未来的研究进行展望。

Abstract

This paper focuses on "zero-gap" alkaline water electrolysis with high current density and excellent stability, summarizing recent research progress. We systematically discuss how catalytic activity, electronic conductivity, hydrophilicity, and pore diameter can be optimized to enhance the performance of catalysts/electrodes and diaphragms. Additionally, we propose the influence mechanisms and optimization strategies for industrial-scale applications. Notably, our comprehensive research reveals that electrode pore diameter exhibits completely opposite mechanisms in enhancing bubble transport and the catalyst's intrinsic activity. Diaphragms with improved hydrophilicity significantly reduce cell ohmic resistance. Finally, based on polarization mechanisms, we discuss future prospects and ongoing efforts in this field.
