| Abstract: | A coupled three dimensional theoretical model of vanadium redox flow battery（VRB） is established to simulate distribution patterns of electrolyte fluid flow, active ions concentration, cell＇ s woltage and current during charge and discharge processes with three different stack designs. The results showed that the design of transverse flow channel between stack manifold and its reaction zone could improve the uniformity of the electrolyte＇ s distribution effectively. Meanwhile, the design lowered the reaction concentration polarization and improved battery＇ s charge and discharge efficiency significantly. |
