b) Fig 11. Predicted and experimental data for the 20 cell stack operated at a) 320 mA/cm2 and 1200 cc/min/cell and b) 240 mA/cm2 and 800 cc/min/cell. The model estimated a cost of $305/kWh for the 20 cell stack operating at 320 mA/cm2. A full description of the cost model developed for flow batteries is described in greater details in FY15 Quarter 3 Project Status Summary Report. In FY16, the model was used to predict the flow battery performance at 400 mA/cm2 and compare it to the experimental data. Single cells were fabricated with Nafion 212 and Nafion 211 and tested at 400 mA/cm2 at various flow rates (400-1200 cc/min/cell). The stack energy efficiencies were ~ 73% and ~ 70% for the Nafion 211 and 212 at 800 cc/min/cell, respectively, Figure 8. Slightly higher stack energy efficiencies (~1% increase) can be achieved by increasing the flow rate to 1200 cc/min/cell. The model was used to predict the cost associated with running the stack with Nafion212 and 211 at 400 mA/cm2 and 1200 cc/min/cell. The results are shown in Table 2. Table 2.
