| Abstract: | Ni anode is oxidized by nonsymmetry squar wave pulse current in dilute aqueous of KCI.The surface property of the oxidized Ni anode has been changed and the actual surface area of it has been increased.At 25℃,in 30w/o KOH aqueous,when current density is 2000A/m 2,the evolution oxygen overpotential of the oxidized Ni anode decreases 260mV relative to unoxidized Ni anode. |

| Keywords: | Ni anode evolution oxygen overpotential pulse current |
