SOLID ELECTROLYTE MEMBRANE WITH MECHANICALLY-ENHANCING CONSTITUENTS AND POROUS CATALYTICALLY ENHANCING CONSTITUENTS

摘要

A solid electrolyte ion transport membrane comprising a matrix material which conducts at least one type of ion such as oxygen ions, and at least one constituent which is physically distinguishable from the matrix material and which enhances the mechanical properties, the catalytic properties and/or the sintering behavior of the matrix material. The constituent is present in a manner which precludes continuous electronic conductivity through the constituent across the membrane. A porous coating preferably is disposed on the membrane to enhance the rate of surface reactions involving the gaseous species.
