Another aspect of the designs for the bipolar plates and flow fields is that the MEA surface next to the land region between the neighboring flow channels is not directly exposed to the reactant gas flow, or in practical operation, devoid of reactant gas supply. ... water in the MEA structure and flow channel can be removed entirely in the ...
As shown in Fig. 1 (a), a typical VRFB system is composed of a stack, two pumps, and two electrolyte tanks. The stack of a VRFB system consists of multiple unit cells, and a unit cell is composed of electrodes, a membrane, a flow frame, and bipolar plates (BPs), as shown in Fig. 1 (b). In general, carbon felt is used as the electrode material, …
The working temperature affects the performance of PEMFC, so a reasonable and efficient cooling channel is necessary to control the working temperature in an efficient area. In this study, the channel structure of the bipolar plate for PEMFC is analyzed using the FLUENT simulation calculation method. The influence of cell size and …
focus of attention and research. 10 single cells, all-vanadium flow battery half-stack and full stack were assembled[8]. In terms of bipolar plates, two kinds of bipolar plates S1 and S2 were investigated. The graphite felts were mainly investigated for the influence of thickness. Two kinds of graphite felts Z1 and Z2 were studied.

tainly considered the dominant part of the redox flow battery stack. However, the bipolar plates tend to be underestimated both in terms of their technical require-ments and, in particular, their contribution to the cost structure. Graphite composite based bipolar plates are manufactured using highly filled compounds [2].
Redox-active organic molecules are promising charge-storage materials for redox-flow batteries (RFBs), but material crossover between the posolyte and negolyte and chemical degradation are limiting factors in the performance of all-organic RFBs. We demonstrate that the bipolar electrochemistry of 1,2,4-benzotriazin-4-yl (Blatter) radicals …
