This analysis is particularly reported for an electrochemically conductive ultrafiltration membrane and has not been reported for moderately conductive AEMs to date. Note that, ‘r’ — Areal resistance (r = R_mA; where ‘R_m’ is membrane resistance and ‘A’ is area); ‘σ’ — Conductivity of the membrane.
