PEMFC气体泄漏机制及预测模型研究综述
Review of gas leakage mechanisms and predictive models for PEMFC
摘要
Abstract
Proton exchange membrane fuel cells(PEMFCs)offer high efficiency and zero emissions,but gas leakage remains a key challenge limiting their performance and reliability.The mechanisms and influencing factors of interfacial and permeation leakage in PEMFCs have been systematically reviewed.Interfacial leakage is affected by surface roughness,contact pressure,material aging,and assembly errors,and is typically analyzed using contact mechanics and lattice Boltzmann methods.Permeation leakage involves gas dissolution and diffusion within sealing materials and PEM,influ-enced by material microstructure and environmental conditions.Studies indicate that sealing mate-rial properties and assembly processes are critical to system integrity.However,leakage behavior un-der coupled thermal-mechanical-chemical fields is still underexplored.Future work should inte-grate advanced testing methods,molecular simulations,and intelligent diagnostics to develop high-performance sealing materials and predictive models,thereby improving the reliability and engineer-ing applicability of PEMFCs.关键词
