Proton NMR measurements of TI, T 1 p and T 2 in "Nation" perfluorosulphonate membranes, together with neutronscattering and dielectric data, show that the aqueous phase in Nation solidifies at a glass transformation whose temperature Tg is 168 K in water-saturated acid membranes. Tg is higher for th
