Nafion membranes have been most widely used as a PEM in fuel cells.

本文提出一种制作燃料电池膜电极组件的新方法。

The pretreated Nafion 115 membrane with a thickness of 125 m was employed in this work.

这样不知道有没有你想要的答案预处理115的全氟磺酸膜厚度为125微米，采用了这项工作。

Nafion, however, can be expensive and it allows some methanol to seep through, which wastes fuel.

然而，Nafion很昂贵而且能渗透过去一些甲醇，造成燃料的浪费。

A Nafion emulsion method for fuel cell membrane-electrode-assembly preparation was reported for the first time in this paper.
