Abstract: A zipped ion-exchange membrane (Z-IEM) having at least one cation-exchange polyelectrolyte (CEP) crosslinked with at least one anion-exchange polyelectrolyte (AEP), wherein the CEP has a molar fraction of positive charges (x) so that: (i) when x=0.5, the Z-IEM is a completely neutralized ion-exchange membrane; (ii) when x>0.5, the Z-IEM is a cation-conducting ion-exchange membrane; (iii) when x
