摘　　要：氯碱工业是我国基础原材料工业,在国民经济中发挥着举足轻重的作用。降低阴极高析氢过电位是目前氯碱工业节能降耗、提高企业经济效益的关键。在最近十几年中,活性阴极技术的研究与应用日益受到人们的重视。影响镍基析氢活性电极性能的主要因素有两种:一是电极材料结晶结构的影响;二为电极真实比表面积的影响,当电极材料的真实表面积远大于表观面积。本文综上了阴极析氢电极在专利申请上的发展历程,从而有助于阴极析氢电极研究人员了解该技术专利动向。Chlor-alkali industry is the basic raw material industry, plays a pivotal role in the national economy. Reduce high cathodic hydrogen evolution overpotential is the chlor-alkali industry energy consumption, improve key economic efficiency of enterprises. In the past ten years, the active cathode technology research and application of increasing people＇s attention. The main factors influencing the activity of Ni-based hydrogen evolution electrode performance in two ways First, the influence of the crystal structure of the electrode material; a second electrode surface area of the real impact, when the real surface area of the electrode material is much greater than the apparent area. In this paper, a summary of the cathode electrode for hydrogen evolution in the patent application development process, thus contributing to the cathode electrode hydrogen evolution researchers understand the technology patent trends.
