Serpentine and interdigitated flow fields are the most frequently studied and compared designs. It is found that the overall battery performance heavily depends on the balance between the electrochemical polarizations and pumping work . More significantly, there exist many issues when scaling up the flow cell toward the stack-scale batteries.
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.
However, the effects of flow fields on distribution in single battery and in stack are different. The distribution uniformity is decreased in the order of IFF > SSFF>No-FF for single battery while the distribution uniformity along cell number is decreased in the order of No-FF > SSFF>IFF for stack.
