Influence of Convection and Material Properties in Vanadium Redox Flow Batteries
Flow field design is one such area where an opportunity for optimization exists for mass transport and system pressure drop. Such optimization can be experimentally explored, as well as computationally2. This combined experimental and computational study that will be presented will show that optimal flow field design is not simply related to the architecture, but is instead a more complex interplay between architecture, electrode properties, electrolyte properties, and operating conditions. The results of this study should be useful to design engineers seeking to optimize VRB systems through enhanced performance and reduced pressure drop.
