Abstract
⺠Water diffusion is the same for Nafion in Na+ and K+ forms for a given water content. ⺠At a given water content, diffusion is faster in the acid form as compared with diffusion in sodium or potassium forms. ⺠The amount of protons within Nafion in acid form by NMR is higher than that by weighing method. ⺠The lability of water in the acid form is more effective than in sodium or potassium form. ⺠A specific behavior of water surrounding each counter-cation is clearly observed by 1H NMR.
