Title of Invention	"HYDROGEN PURIFICATION DEVICES,COMPONENTS AND FUEL PROCESSING SYSTEMS CONTAINING THE SAME.
Abstract	A hydrogen purification device,components thereof, and fuel processor and fuel cell system containing the same. The hydrogen purificationdevice include an encloser that contains a separation assembly adapted to receive a mixed gas stream containing hydrogen gas and to produce a system that contains pure or at least substantially pure hydrogen gas therefrom. The seoaration assembly includes at least one hydrogen-permeable and/or hydrogen-selective membrane, and in some embodiments includes at least one membrane envelop that includes a pair of generally opposed membrane regions that define a harvesting conduit therebetween and which are separated by a support. The enclosure includes components that areformed from materials having similar or the same coefficients of thermal expansion as the membrane or membranes. In some embodiments, these include at least a portion of the support, and in some embodiments, these components include at least a portion of the enclosure.
