• The relationship between the transport properties of various salt forms (H + , Li + , Na + , Cs + ) of MF-4SC hybrid membranes containing nanoparticles of crystalline acid zirconium phosphate Zr(HPO 4 ) 2 at various relative humidities are investigated with the use of impedance studies and NMR spectroscopy. Modification of the membranes leads to a marked increase in ion mobility, and the maximum effect is observed under reduced humidity conditions. The conductivity of a modified membrane at a relative humidity of 10% is 1.6 × 10 −4 Ω −1 cm −1 , that is, almost 1.5 orders of magnitude greater than the conductivity of an initial membrane under the same conditions.
