Figure 7. Charge and discharge voltage performance for single cells with Nafion 211 and 212 with flow rates of 1200 cc/min/cell and current densities of a.) 320 mA/cm2 and b). 400 mA/cm2. As shown in Figure 7, there is a difference in performance of the Nafion membranes at both current densities. The voltage on charge and discharge is smaller for the Nafion 211 membrane at a given capacity; more capacity can be attained at a given cut off voltage window. At the largest capacities (~ 20 Ah/l), however, the voltage on charge and discharge becomes similar. Both Nafion membranes show nonlinear behavior at the highest capacities; suggesting that these losses are attributed to the electrode overpotentials. Shown in Figures 8 and 9 are the coulombic, voltage, and energy efficiencies for the cells fabricated with Nafion 211 and 212 as a function of flow rate at 320 mA/cm2 and 400 mA/cm2. 11PDF Image | High Current Density Redox Flow Batteries
