摘要：
Understanding ion transport in Anion Exchange Membranes (AEMs) has been a widely researched area. In this work we have utilized the method of F-19 diffusion NMR to our advantage for this purpose. Fluoride ion and hydroxide ion have similar ionic sizes which makes it as an ideal replacement for the caustic anion. In particular we have studied the effect of temperature and increasing diffusion times (.) on self diffusion of fluoride ions. We have also made a unique effort at measuring bicarbonate and carbonate diffusion through AEMs in this article.
