ABSTRACT:
Composite ceramic mixed ionic and electronic conducting materials having high ambipolar activity which can be fabricated into thin membranes for high efficiency oxygen separation from air at intermediate temperatures. The mixed conducting materials have composite non-homogeneous microstructures of a separate predominantly oxygen ion conductive phase and a predominantly electronic conductive phase. Preferred predominantly oxygen ion conducting phases include bismuth, cerium and zirconium oxide based materials and predominantly electronic conducting phases include at least one metal electronic conductor material.
