Controlling Chloride Crossover in Bipolar Membrane Water Electrolysis.

ABSTRACT: Bipolar membranes (BPMs) are increasingly recognized as a promising electrolyte option for water electrolysis, attributable to their distinctive properties derived from the membrane's layered structure, which consists of an anion exchange (AEL) and a cation exchange layer (CEL). This study investigates four different BPMs and the influence they have on the performance of a water electrolysis cell under two different feed configurations: (1) a symmetric deionized water feed to both anode and cathode compartments and (2) an asymmetric feed with a 0.5 mol/L NaCl catholyte feed and a deionized water anolyte feed. The BPMs were also investigated for total chlorine (Cl) species (e.g., Cl^-, Cl₂, HOCl, and ClO^-) in the anolyte due to Cl^- crossover from t
