Abstract
The characteristic of oxide layer formed on the surface of metal in Metal|Solid Electrolyte|Gel Membrane Containing Water|Graphite System was studied by using Point Defect Model and Barrier Layer/Porous Layer Model.Trace water in solid electrolyte helped to form porous layer at the surface of metal,The thickness of porous layer increased due to water molecule reacts with barrier layer continuously,which lowered the porosity and decreased the electromotive potential and current.Porosity influenced solubility behavior of oxide layer intensely.Like barrier layer,porous layer is also a semiconductor.
