Abstract

Hydrogen purification devices, components thereof, and fuel processors, fuel processing systems, and fuel cell systems 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. In some embodiments, the separation assembly includes at least one hydrogen-permeable and/or hydrogen-selective membrane. In some embodiments, the fuel processors, fuel processing systems, and/or fuel cell systems include at least one modular, or cartridge-based component. In some embodiments, the hydrogen purification device is, and/or includes, a modular, or cartridge-based, component. In some embodiments, the hydrogen purification device includes components that are formed from materials having the same or similar coefficients of thermal expansion.
