@65dBnoise then for the cell test: "S1.5 Flow cell tests Nafion membranes were first treated with 5% H2O2 solution at 80 °C for 1 h to eliminate impurities. Subsequently, the membranes were transferred to 5% H2SO4 and incubated at the same temperature for another 1 h. Finally, the H-type Nafion was converted to the K-type by immersion in 1 mol/L KOH aqueous solution at 80 °C for 1 h. AIFB tests were performed using a home-made cell containing carbon felt electrodes (square cuboid 70 × 40 × 3 mm with 95.5% porosity) with a geometrical surface area of 28 cm2, composite graphite current collectors and ion-exchange membrane (Nafion 212). The catholyte (20.0 mL) and anolyte (20.0 mL) were pumped at a flow rate of 100.0 mL min-1. The charge process was limited by a charge capacity of 65% of the theoretical capacity or cut-off voltage of 1.65 V to avoid overcharge and the side reaction. The discharge cut-off voltage is 0 5 V, which makes the battery discharge completely. "
