<p>A hydrogen purification device (10) includes enclosure (12) that contains a separation membrane assembly (20) adapted to receive a mixed gas stream (24) containing hydrogen gas to produce a stream (34) that contains pure or at least substantially pure hydrogen gas therefrom. Separation assembly (20) includes at least one hydrogen-permeable and/or hydrogen-selective membrane (46), and in some embodiments includes at least one membrane envelope that includes a pair of generally opposed membrane regions that define a harvesting conduit therebetween and which are separated by a support. The enclosure (12) includes components that are formed from materials having similar or the same coefficients of thermal expansion as the membrane or membranes (46). In some embodiments, these components include at least a portion of the support, and in some embodiments, these components include at least a portion of enclosure (12).</p> |
