Abstract
A hydrogen purification device, components thereof, and fuel processors and fuel cell system containing the same. The hydrogen purification devices include an enclosure that contains a separation assembly adapted to receive a mixed gas stream containing hydrogen gas and to produce a stream that contains pure or at least substantially pure hydrogen gas therefrom. The separation assembly may include at least one hydrogen-permeable and/or hydrogen-selective membrane, In some embodiments, the enclosure includes a pair of end plates and a shell extending generally between the end plates. In some embodiments, the enclosure includes a shell that is integrated with at least one of the end plates. In some embodiments, at least one of the end plates includes a deflection and/or stress abatement structure. In some embodiments, the device includes components formed from materials having similar or the same coefficients of thermal expansion.
