Abstract

It was shown that the swelling of the initially hydrophobic Nafion plate in ordinary water (157 ppm deuterium content) and in deuterium-depleted water (1 ppm deuterium content) in a limited volume cell occurs differently. It turned out that small changes in the deuterium content in water lead to significant differences in the dynamics of swelling of the polymer membrane. For a 175-micron thick Nafion plate, this effect is most pronounced when the distance between the windows is L = 200 microns.
