电解水制氢技术概述及发展现状

Technology Overview and Development Status of Hydrogen Production from Water Electrolysis

由于传统化石燃料的不可再生性以及燃烧释放CO_(2)所带来的环境问题,需要积极发展新能源来替代传统能源。氢能具有热值高、来源广泛以及可持续发展等优点,因此备受人们青睐。在各类H_(2)制备技术中,电解水工艺简单,生产全程无污染,是制备H_(2)的重要发展途径。本文介绍了电解水制氢的原理并分析电解水制氢的影响因素,同时分别从阴极析氢材料、阳极析氧材料以及电解池系统三个方面来阐述目前电解水制氢技术的发展现状。

Due to the non-renewable nature of traditional fossil fuels and the environmental problems caused by the release of carbon dioxide from combustion,new energy sources need to be actively developed to re-place traditional energy sources.Hydrogen energy is highly preferred because of its high calorific value,wide range of sources and sustainability.Among the various hydrogen preparation technologies,electrolysis of water is an important development pathway for the preparation of hydrogen because of its simple process and pollution-free production process.This paper introduces the principle of hydrogen production from electrolytic water and analyzes the influencing factors of hydrogen production from electrolytic water,and describes the current development status of hydrogen production from electrolytic water in three aspects:cathode hydrogen precipi-tation material,anode oxygen precipitation material and electrolytic cell system.
