Abstract
A method is described of producing a composite oxygen ion membrane and a composite oxygen ion membrane in which a porous fuel oxidation layer and a dense separation layer and optionally, a porous surface exchange layer are formed on a porous support from mixtures of (LnA)CrBOand a doped zirconia. Preferred materials are (LaSr)CrFeOfor the porous fuel oxidation layer, (LaSr)CrFeOfor the dense separation layer, and (LaSr)CrFeOfor the porous surface exchange layer. Firing the said fuel activation and separation layers in nitrogen atmosphere unexpectedly allows the separation layer to sinter into a fully densified mass.
