PEMFC密封材料与结构设计研究综述
Review of PEMFC sealing materials and structural design
摘要
Abstract
The reliability of the proton exchange membrane fuel cell(PEMFC)sealing system is cru-cial to its operation and commercialization,and related research has been carried out from three as-pects.At the material level,the characteristics of silicone rubber,fluoroelastomer and other materials were compared,and the application value of new sealants such as UV light-curing adhesive and an-aerobic adhesive was discussed.In terms of structural design,based on the interfacial stress and as-sembly process,the advantages and disadvantages of direct sealing,MEA/PEM wrapping and rigid frame structures were analyzed.In the durability assessment,the chemical degradation,fatigue and stress relaxation mechanisms of the sealing system under acid corrosion,heat-wetting cycle,and dy-namic load are described.Future research can focus on composite material design,interface mechan-ics optimization and multi-scale life prediction,and provide theoretical and practical guidance for the optimization of sealing systems.关键词
