Performance Characterization of a Vanadium Redox Flow Battery at Different Operating Parameters under a Standardized Test-Bed System
This paper describes the experimental characterization of a 25 cm2 laboratory scale vanadium redox flow battery (V-RFB). The unit cell performance with respect to voltage, coulombic and energy efficiencies under different performance parameters (current densities, operating temperatures, flow rates,...
