The preparation and characterization of polymeric anionic membranes for alkaline fuel cells were investigated. Starting from chloromethylated aromatic polymer (PSU), we introduced anionic exchange groups by reaction with different kinds of amines. The characterization was done studying various chemical and physical parameters of the membrane using various techniques like NMR and impedance spectroscopy, TGA and water uptake measurements. Good results are obtained in terms of stability and ionic conductivity; the amines utilized and the degree of chloromethylation of the polymer strongly influence the final properties.
