介绍
薄质子交换膜具有优异的性能,包括低电阻率、高质子传导率和最小氢渗透电流密度,可确保较长的使用寿命。这种膜可用于质子交换膜(PEM)燃料电池、直接甲醇燃料电池(DMFC)和水电解槽。在电化学电池中,它的主要作用包括分隔负极和正极,同时充当固体电解质。此外,它还能选择性地将阳离子输送到电池接面。值得注意的是,有几种非增强型 Nafion 膜可供选择,如 N117、N115、NR212 和 NR211,每种膜的厚度尺寸各不相同。选择合适的膜厚度取决于具体因素,包括所需的跨膜压降、与氧气生成有关的大气、膜支持类型和预期运行寿命。适当考虑这些因素将为成功应用提供最佳选择。

N211、N212 和 NC700 以上型号有两层保护膜。
使用前可进行预处理。具体方法是:先用 5%的双氧水在 80℃下处理 1 小时,然后在去离子水中浸泡半小时,再用 5%的稀硫酸(质量比)在 80℃下煮 1 小时,最后在去离子水中浸泡半小时。
