應用

Nafion^™是一种全氟离子交换膜，具有多种商业用途。酸性（氢离子）形式和衍生物是固体超强酸催化剂，可用于多种合成应用中。

Nafion^™ perfluorinated membrane is mainly used as a proton exchange membrane (PEM) for fuel cell applications. It can also be used as a membrane for lithium isotope separation, which can be further be utilized as a fuel for fusion reactors. It has excellent chemical stability and high cationic conductivity. It finds potential usage in batteries and sensors.[1][2][3]

Surface that is shiny and smooth must be installed facing the cathode.

包裝

由于有机物的吸收，在一般室内环境中长时间（几个月）存放的膜通常会变暗/变褐色。在储存期间，应确认产品是否保持密封。
· 保持膜密封并防止一般暴露，可减少有机物的影响。长期储存时，建议使用密封袋存放。
· 变色不影响性能，使用稀硝酸浸泡可除去颜色。
