Prospects of flow field design for RFB have been exhibited. Flow field is an important component for redox flow battery (RFB), which plays a great role in electrolyte flow and species distribution in porous electrode to enhance the mass transport. Besides, flow field structure also has a great influence in pressure drop of the battery.
Besides, flow field structure also has a great influence in pressure drop of the battery. Better flow field not only can improve the mass transport in electrode but also is able to decrease the pressure drop of RFB.
