HYDROGEN PURIFICATION DEVICES, COMPONENTS, AND FUEL PROCESSING SYSTEMS CONTAINING THE SAME Hydrogen purification devices, components thereof, and fuel processors and fuel cell systems containing the same. The hydrogen purification devices include an enclosure, such as a pressure vessel, that contains a separation assembly that receives under pressure a mixed gas stream containing hydrogen gas and produces a stream that contains pure or at least substantially pure hydrogen gas therefrom. In some embodiments, the enclosure is sealed without gaskets. The separation assembly includes at least one hydrogen-permeable and/or hydrogen-selective membrane. In some embodiments the hydrogen-selective membrane is permanently and directly secured to the enclosure or a perimeter shell. In some embodiments, the membrane is welded, diffusion bonded or brazed directly to the enclosure or shell. In some embodiments, a portion of the membrane forms a portion of a seal and/or the sealed enclosure. In some embodiments, an interface is formed from consumed portions of the hydrogen-selective membrane and the enclosure or shell.
