Performance Analysis and Monitoring of Vanadium Redox Flow Battery via Polarization curves

This article proposes the demonstration and deployment of a hand-tailored vanadium redox flow battery test station to investigate effect applied voltages on charging performance for electrolyte preparation reactant rates balance system capacity. Herein, two different specifications membranes number electrode layers playing pivotal roles in discharging characteristics VRFB were observed as well. Results indicated that 1.70 V voltage was suitable, when optimized considered from time, current, mole electrons. The rate (10 mL/min) must be controlled since it corresponds mass transfer diffusion, resulting reaction ability surfaces. influenced active areas diffusion electrolytes. Nafion 212 provided superior 117, because possessed lower ohmic resistance allowed easier proton transfer.
