Fig. 6. Dependences of the voltage (a) of the VVPB cell with the MEA of the composition Pt-C (0.226 mg/cm2)|Nafion 211|CP 6 x 0.28 mm and the potentials of its half-cells relative to the Ag/AgCl reference electrode (b) during the galvanostatic charge/discharge test at ±0.8 A (±200 mA/cm2) for a linear flow rate of vanadium electrolyte of 3 cm/s (65 ml/min), 6th cycle. Solid lines are the curves obtained during charging, dashed lines are during discharging. Dots are the result of measuring the voltage and open-circuit potentials of half-cells at different SOC (data from Fig. 3). |
