A critical analysis of transport properties (diffusion, osmotic flux, conductivity, permeability) of Nafion membrane was carried out. Several correlations were elaborated to provide a consistent description of these properties in a wide range of electrolyte concentrations and membrane hydration states. A model for a sulfur dioxide depolarized electrolyzer (SDE) based on these new equations has been validated by experiments carried out with different electrode materials and electrolytes.
