The mass transfer process of VO2+ in Nafion117 was studied

this work focused on the synergistic effect of concentration field and electric field in different operating conditions. Influence of electric field on the mass transfer process across membrane of VO2+ is oberserved

and the apparent electric mobility of VO2+ in Nafion117 was estimated based on experimental data. The results show that

the force of electric field on the VO2+ mass transfer process across membrane in high concentration condition is more obvious than that in low concentration condition. Increasing temperature as well as electrolyte convection can strengthen electric field effect on membrane crossing process of VO2+. The mass transfer process in membrane of VO2+ is accelerated by increasing additional positive electric field force

and the electric factor increases with time. Negative electric field can help alleviate the phenomenon of mass transfer process across membrane of VO2+.
