摘要：A method of producing a composite oxygen ion membrane and a compositeoxygen ion membrane in which a porous fuel oxidation layer and a dense separation layerand optionally, a porous surface exchange layer are formed on a porous support frommixtures of (LnA)CrBO and a doped zirconia. In the porous fuel oxidation layer and the

optional porous surface exchange layer, A is Calcium and in the dense separation layer Ais not Calcium and, preferably is Strontium. Preferred materials are (LaCa)CrMnO for theporous fuel oxidation and optional porous surface exchange layers and (LaSr)CrFeO forthe dense separation layer. The use of such materials allows the membrane to sintered inair and without the use of pore formers to reduce membrane manufacturing costs. Theuse of materials, as described herein, for forming the porous layers have application forforming any type of porous structure, such as a catalyst support.
