In the experiments of Fourier IR spectrometry we studied the swelling mode of the Nafion polymer membrane in water poured into cuvette, the characteristic size of which is on the order of the membrane thickness. The interest in these studies is due to the fact that when Nafion swells in a cell whose size is much larger than the membrane thickness, there is an effective “unwinding” of polymer fibers into the volume of water [1]. However, this process has not been studied in the case where the area that the unwound polymer fibers can occupy is limited by the size of the cuvette. It is shown that, in this case, the temporal dynamics of the transition of the polymer from the hydrophobic to the hydrophilic state has a number of specific features that depend on the size of the cell, as well as on the isotopic composition, ion content, and pretreatment of water. The polymeric membranes impregnated with water, the study of which is devoted to this work, are widely used in low-temperature hydrogen power engineering, in electrolyzers, hydrogen generators, as well as in hydrogen fuel cells.
