POROUS SUPPORT LAYER

摘要

A porous support layer for a composite oxygen transport membrane, said support being comprised of a fluorite structured ionic conducting material having a porosity of greater than 20 percent and a microstructure exhibiting substantially uniform pore size distribution throughout the porous support layer, wherein the porous support layer is formed from a mixture comprising fluorite structured ionic conducting material or from a mixture comprising polymethyl methacrylate based pore forming material and a fluorite structured ionic conducting material, said polymethyl methacrylate based pore forming material and/or said fluorite structured ionic conducting material having bi-modal or multi-modal particle sizes.
