Hence, the collaboration of manufacturers and research institutes should be intensified, in order to make sure that the presented virtual models also unfold an actual practical benefit. Regarding the model extensions, the plug flow reactor principle can overcome the simplification of a perfectly mixed cell [19, 100]. Further, first works try to capture the topic of ageing [27]. For long-term operation, the effect of bulk electrolyte and water transfer across the membrane should be included in lumped-parameter models, e.g. as shown in [24]. The standard electrolyte is an oversaturated solution. Thus, a certain temperature window has to be kept in order to prevent the precipitation of the vanadium salts. Consequentially, sophisticated thermal models of the VRFB are of high interest and should be included in future studies. 145PDF Image | Model-based Design Vanadium Redox Flow Batteries
