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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
