Abstract
An ion-transport membrane assembly including a tubular, ion-transport membrane that is fabricated from one or more ion-transport, ceramic materials capable of ionic transport at an operational temperature of greater than 400° C. The membrane may be an oxygen transport membrane or a hydrogen transport membrane. A plurality of structural supporting members, fabricated from an open porous material and having an outer cylindrical surface, are inserted within the membrane, without being bonded to the membrane, to inhibit inward collapse of the membrane under application of a pressure applied to an exterior surface of the membrane. The structural supporting members are configured to permit relative movement between the outer surface of the structural supporting member and the interior surface of the tubular membrane during heating to or cooling from the operational temperature thereof.
