Perfluorinated ion exchange membranes, such as Nafion, are currently the object of intense interest due to their potential use as separators in fuel cells. It is well known that the presence of water in these membranes enhances the protonic conductivity, however, a detailed understanding of the role of water in protonic transport is still incomplete. As a contribution to this problem the authors will discuss the dependence of dielectric relaxation, deuteron and oxygen-17 T{sub 1} NMR relaxation times on both pressure and water content.
