质子交换膜电解水制氢双极板涂层的研究进展
Research Progress on Bipolar Plate Coatings for Proton Exchange Membrane Water Electrolysis for Hydrogen Production
摘要
Abstract
Proton exchange membrane water electrolysis for hydrogen production is highly compatible with the fluctuating input of renewable energy and represents one of the key technologies for achieving the"dual carbon"goals.However,in the service environment of high potential,strong acidity,and high oxygen concentration,the bipolar plates,as the core components of the electrolyzer,are prone to corrosion on their surfaces,forming low-conductivity oxide films through passivation,which significantly increases the contact resistance between components,thereby reducing the efficiency of electron transfer and increasing the energy consumption for hydrogen production.At the same time,high-potential operation can easily induce local hotspots,which may cause membrane electrode perforation and short circuits,and even pose a risk of hydrogen-oxygen mixture explosion.Coating technology can effectively suppress corrosion,reduce contact resistance,extend the service life of the electrolyzer,and enhance the safety of hydrogen production by constructing a dense protective layer on the surface of the bipolar plates.However,there are currently a wide variety of coating materials and preparation processes,and how to balance high conductivity,corrosion resistance,and low cost,while achieving a dense and uniform coating with high adhesion to the substrate,remains a core challenge in this field.This paper systematically reviews the research progress of coating technology for bipolar plates in proton exchange membrane electrolyzers,focusing on the performance characteristics of various coating material systems,the advantages and disadvantages of different coating processes,their optimization strategies,and standardized performance evaluation methods for coatings.In combination with current industrial demands,it summarizes the bottlenecks of bipolar plate coating technology in practical applications,such as coating defects,lack of large-scale validation,and insufficient long-term service stability,and looks forward to its future technological development directions,with the aim of providing a reference for the development and application of the next-generation bipolar plate coating technology.关键词
