Abstract

Water transport in proton exchange membranes (PEMs) is relevant to several advanced technologies, especially fuel cells. The dynamics of changing water conditions can significantly impact the PEM conductivity and fuel cell performance. Accurate water diffusion coefficients in Nafion, the industry standard PEM, have been determined, non-Fickian regimes identified and modeled, and infrared data used to confirm the validity of these models. ©The Electrochemical Society.
