Ceramic Appliques for the Production of Supported Thin Film CMRs

DOE Phase II Contract No. DE-FG03-00ER82996

This project addressed the separation of oxygen from air using a dense thin film ceramic membrane. These membranes offer the advantage of higher oxygen flux at lower temperatures than current dense ceramic membranes. The selectivity of the dense ceramic membranes are superior to that of low temperature polymeric membranes. Mixed ionic and electronic conducting materials developed at Eltron Research have been fabricated into dense membranes which exhibit high oxygen flux in catalytic membrane reactors. To commercialize these materials, fabrication techniques for producing operationally stable thin films must be developed. All aspects necessary for successful reactor operation were addressed in the Phase II project. These included: improved porous support formulations, better match of film applique and porous support sintering properties, catalyst composition and deposition techniques, and membrane scale up.
