<p>Hydrogen purification devices, components thereof, and fuel processors andfuel cell systems containing the same. The hydrogen purification devices includean enclosure (12), such as a pressure vessel, that contains a separation assembly(20) adapted to receive under pressure a mixed gas stream (24)containing hydrogengas and to produce a stream that contains pure or at least substantially pure hydrogengas (34) therefrom. In some embodiments, the enclosure is sealed without gaskets.The separation assembly includes at least one hydrogen-permeable and/or hydrogen-selectivemembrane (46), and in some embodiments the hydrogen selective membrane is permanentlyand directly secured to the enclosure. In some embodiments, the membrane is welded,diffusion bonded or brazed directly to the enclosure. In some embodiments a portionof the hydrogen-selective membrane forms a portion of the sealed enclosure,and, in some embodiments, an interface is formed from consumed portions of thehydrogen-selective mem brane and the enclosure.</p> |
