Since most of the water source onthe earth surface issaline innature,hydrogen generation from saline water is ofgreat importance.Inthis paper,wehave developed amembrane protected anode,using anionic backbone ofsulfonated polystyrene-block-(ethylene-ran-butylene)-block-polystyrene polymer (S-PSEBS) over the anode (IrO2/Ti) which iscapable ofelectrostatically repelling the chloride ions (Cl) from the electrode surface and thereby enhancing the oxygen evolution rather than the chlorine evolu- tion. The electroche mical behavior ofboth polymer modifiedand bare IrO 2/Ti electrodes were characterized by electroche mical polarization studies and the gas evolution efficiencieswere calculated.The surface morpholog yofthe electrodes was investigated usi ngscanning electron microscope (SEM).The results suggest that nearly 95%oxygen evolutio nefficiencycould beachieved when the surface of IrO2/Ti electrode was modifiedwith apermselective membrane
