摘要:
The invention concerns a method for preparing a solid composite electrolyte consisting of at least a compound of the BIMEVOX family characterised in that it comprises: a) at least a step which consists in preparing a mixture of one or several compounds of the BIMEVOX family with one or several chemically inert compounds; b) at least a step which consists in compacting the mixture resulting from step a); c) at least a sintering step during which the temperature reaches, for a non null time interval, a value higher than the optimal temperature for sintering said compound of the BIMEVOX family.
摘要:
The invention concerns a method for separating oxygen from a mixture of gas containing said oxygen, using an electrochemical cell with solid electrolyte, characterised in that said cell comprises a homogeneous structure consisting of one or several BIMEVOX derivatives, with reversible and self-adaptive dynamic electrodes generated 'in situ' and at least two current collectors. The invention also concerns the electrochemical cell for implementing the method and its applications.
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 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 characterised 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.
