摘要
质子交换膜是燃料电池中的关键部件,其主要作用是质子传导.该文基于分子动力学模拟研究水含量对质子传导的影响.研究结果表明:随着水含量λ增加,磺酸基团中的硫原子-水分子中的氧原子、磺酸基团中的硫原子-水合氢离子中的氧原子的径向分布函数随之减小,形成的团簇不断增大,这能有效提高质子的传导效率.
Proton exchange membrane is a key component of fuel cells,and its main function is proton conduction.So in this paper,the influence of water content of proton exchange membrane on proton conduction is studied based on molecular dynamics simulation.The research results indicate that with the increase of water contentλ,the radial distribution functions between sulfur atoms(in sulfonate groups)and oxygen atoms(in water molecules),and between sulfur atoms(in sulfonate groups)and oxygen atoms(in hydronium ions)decrease,but the cluster sizes increase,which can significantly improve the efficiency of proton conduction.
