Abstract
The invention concerns an oxide ion conductive ceramic membrane, characterized in that it comprises a non-null finite volume with non-null total thickness E, comprising, a dense layer (CD) of a solid electrolyte, a so-called bonding layer (CA), of mixed conductive porous cathode (EP) and porous anode (EP'), a cathode current collector (CC) and an anode current collector (CC′), a coating porous layer (ER), and a coating porous layer (ER′), and characterized in that the volume E of said membrane, is equal to the sum of the thickness of said elements. The membrane is used for separating oxygen from air or from a gas mixture containing same and in particular for producing ultra-pure oxygen under high pressure in a closed chamber.
