COMPOSITE MIXED OXIDE IONIC AND ELECTRONIC CONDUCTORS FOR HYDROGEN SEPARATION

摘要

A mixed ionic and electronic conducting membrane includes a two-phase solid statec ceramic composite, wherein the first phase comprises an oxygen ion conductor and the second phase comprises an n-type electronically conductive oxide, wherein the electronically conductive oxide is stable at an oxygen partial pressure as low as 10^-20 atm and has an electronic conductivity of at least 1 S/cm. A hydrogen separation system and related methods using the mixed ionic and electronic conducting.
