How does flow field geometry affect redox flow batteries?

Author to whom correspondence should be addressed. In vanadium redox flow batteries, the flow field geometry plays a dramatic role on the distribution of the electrolyte and its design results from the trade-off between high battery performance and low pressure drops.

Is outlet fluid enthalpy suitable for battery cooling plate topology optimization?

Using outlet fluid enthalpy is recommended as the optimal objective function for topology-optimized cooling plates, providing an effective solution for battery cooling plate topology optimization. Wang et al. conducted research aimed at optimizing microchannel reactors for both Newtonian and non-Newtonian fluids.

Does a symmetric cell configuration affect the battery state of charge (SOC)?

Membrane permeable to only protons and not permeable to vanadium ions, since in the symmetric cell configuration the net vanadium flux through the separator is negligible and moreover it does not affect the battery state of charge (SoC). Laminar flow regime due to the reduced electrolyte velocities expected from the investigated flow rates.

How does Interdigitated geometry affect battery performance?

Battery performances are regulated by a complex interplay of kinetic and mass transport phenomena, occurring with a different intensity throughout the cell active area. Considering CFD simulations, Interdigitated geometry presents higher electrolyte velocities, while Two Outlets and Four Inlets guarantee a more even electrolyte distribution.

How do Inlet and outlet configurations affect topology optimization results?

Inlet and outlet configurations impact topology optimization results. Reasonable inlet and outlet structures achieve lower temperatures and uniformity. Rational inlet and outlet structures minimize resistance losses. Sensible inlet and outlet structures effectively enhance heat transfer capability.

Can a computational fluid dynamics model predict electrolyte mass transport?

In a recent work by the authors [ 14 ], a computational fluid dynamics (CFD) model was coupled with local performance characterization, permitting analysis of the cell operation at the local level with different flow field configurations and thus strengthening the understanding of the physical phenomena regulating electrolyte mass transport.
