Abstract

to water penetration may be thermodynamic or kinetic in origin. One might expect that the PEM surface will become increasingly hydrophilic as the relative humidity (RH) of the air increases, but there are no quantitative studies of this effect. Predicting this is challenging, due to the fact that thermodynamic equilibrium is influenced by factors other than surface tension of the dry domains, such as chain connectivity, entropy, and domain geometry.
