Estimating the term…
A multi-phase solid electrolyte ion transport membrane comprising at least two phases wherein one of the phases comprises an oxygen ion single conductive material, or a mixed conductor. The other phase comprises an electronically-conductive metal or metal oxide that is incorporated into the membrane by deposition of the metal or metal oxide from a polymer made by polymerizing a chelated metal dispersion in a polymerizable organic monomer or prepolymer. The multi-phase composition advantageously comprises a first phase of a ceramic material and a second phase of a metal or metal oxide bound to a surface of the ceramic material. The multi-phase composition is advantageously prepared in an in-situ fashion before fabricating the membrane matrix. As another alternative, a preformed ceramic matrix is surface-coated with a metal or metal oxide.
A method for fabricating a multi-phase solid electrolyte ion transport material comprising a granulated first phase coated with a second phase, the first phase comprising an ionic conductor or mixed ionic/electronic conductor and having a surface consisting of a plurality of granule surfaces, the second phase comprising metal particles of at least one metal or metal oxides, the method comprising the steps of:
A multi-phase solid electrolyte ion dense or porous matrix comprising:
A method for fabricating a multi-phase solid electrolyte ion transport membrane, an ion transport membrane having a porous catalytic surface exchange enhancement, or a porous solid oxide fuel cell electrode which comprises the steps of:
