a, Water migration behaviour under different concentrations of H2SO4 solution (50 wt% KOH solution as the initial SDE). Each mean value was calculated from three measurements. b, Electrolysis durability in 0.5 M H2SO4 solution. c, The water migration behaviour under different concentration of NaOH solution (50 wt% KOH solution as the initial SDE). Each mean value was calculated from three measurements. d, Electrolysis durability in 0.5 M NaOH solution. e, The water migration behaviour under different concentrations of NaCl solution (50 wt% KOH solution as the initial SDE). Each mean value was calculated from three measurements. f, Electrolysis durability in saturated NaCl solution.
