摘要：

A model of transport across the ion-exchange membrane in allvanadium redox flow batteries has been proposed based on concentrated solution theory for species with high concentration. The model is based upon the Stefan-Maxwell multicomponent diffusion equation where the fluxes of the species including protons (H+), bisulfate (HSO4-), water (H2O) and the sulfonate functional groups (-SO3-) are fully coupled. The driving force for species transport has been modeled in terms of concentration and electrostatic potential gradients. The ionic transference numbers as well as water electro-osmosis drag coefficient has been calculated for different acid concentrations.
