Flow battery stack design

Can redox flow battery stack models be accurate?

Author to whom correspondence should be addressed. Current redox flow battery (RFB) stack models are not particularly conducive to accurate yet high-throughput studies of stack operation and design.

Which flow cell design is best for a stack-scale battery?

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.

How do flow fields affect distribution in single battery and stack?

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.

How to model a flow battery?

It is worth noting that the channel depth and electrode thickness are taken into account to calculate the velocity magnitude and maintain the mass conservation at the boundary of two regions . Another modeling strategy for flow batteries is to simulate the segmented channels/electrodes with connected flow resistances.
