OXIDE ION CONDUCTIVE CERAMIC MEMBRANE STACKED MICROSTRUCTURES; USE FOR SEPARATING OXYGEN FROM AIR

摘要

The invention concerns an oxide ion conductive ceramic membrane, characterised 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 two porous electrodes (EP) and (EP'), two porous current collectors (CC) and (CC'), and at least at least a coating porous layer (ER), characterised in that the thickness E of the volume of said membrane, is equal to the sum of the thickness of each of said elements. The membrane is used for separating oxygen from air or from a gas mixture containing same.
