A number of MK-40 cation-exchange membrane samples modified with ceria have been obtained. The membranes have been studied using a set physicochemical methods, including impedance spectroscopy, scanning electron microscopy, microanalysis, transmission electron microscopy, and XRD phase analysis. Ithas been shown that the embedding of cerium oxide reduces the humidity content and ionic conduction of membranes. It is accompanied by a marked increase in the membrane selectivity expressed by a decrease in transfer numbers with respect to anions
