Abstract
A cheap and more efficient alkaline water electrolysis technology is based on hydroxide ion conducting membranes can be improved through developments of the electrocatalyst O2(g) evolving anodes and H2(g) evolving cathodes through electrodeposition technique[1]. In addition, the electrodeposition of the metallic thin films on a cathode substrate in an electrolytic cell is widely used in order to obtain metallic coating for corrosion control and good surface finishing as well as increasing strength and the resistance to wear [2]. The electrodeposited oxidation-resistant metallic thin films can be used as anode for metal/air batteries such as cadmium/air, lithium/air, magnesium/air, iron/air, zinc/air, and aluminium/air batteries that are ecofriendly electrical energy sources[3-5]. The thin films electrodeposition provide metallic alloys of low cost and long last cathodes with a very high theoretical specific energy in the neutral or alkaline aqueous media where oxygen gas-reduction reaction is the predominant cathodic reaction[6].
