Abstract: PURPOSE: A nickel oxide-nickel composite membrane for hydrogen separation and a manufacturing method thereof are provided to prevent interdiffusion between a hydrogen separating membrane layer and a surface catalyst layer and to prevent reduction of permeability by suppressing impurities which are generated by interdiffusion between metals. CONSTITUTION: A nickel oxide-nickel composite membrane for hydrogen separation comprises nickel oxide and nickel which are generated by an anodizing method with an organic compound electrolyte. The organic compound electrolyte comprises ethylene glycol, glycerol, diethylene glycol, dimethyl sulphoxide(DMSO), and formamide as a solvent and comprises the nickel oxide and the nickel which include NH4F, HF, NaF, or KF. One side or both sides of the hydrogen segregation composite membrane is coated with a metal which is selected from a group comprised of palladium(Pd), palladium alloy, vanadium(V), vanadium alloy, tantalum(Ta), tantalum alloy, niobium(Nb), and niobium alloy. The nickel oxide acts as a preventing interdiffusion layer between metals. The thickness of the nickel oxide is between 1 micromolar and 3 micromolar in the hydrogen segregation composite membrane. The hydrogen segregation composite membrane is used for separating a gas mixture which is generated after a water gas shift reaction, mixing gas for carbon dioxide depositing, mixing gas for hydrogen refining, and mixing gas which is generated after methane reforming reaction.
