KOH-doped membranes, so-called ion-solvating membranes (ISMs), have been used in alkaline water electrolysers but face challenges with stability and narrow operational windows. Here a non-crosslinked, partially sulfonated polybenzimidazole ISM with enhanced conductivity and stability is reported, achieving high current densities and prolonged operation.
