Hydrogen purification membranes, hydrogen purification devices, and fuel processing and fuel cell systems that include hydrogen purification devices. The hydrogen purification membranes include a metal membrane, which is at least substantially comprised of palladium or a palladium alloy. In some embodiments, the membrane contains trace amounts of carbon, silicon, and/or oxygen. In some embodiments, the membranes form part of a hydrogen purification device that includes an enclosure containing a separation assembly, which is 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 membrane(s) and/or purification device forms a portion of a fuel processor, and in some embodiments, the membrane(s) and/or purification device forms a portion of a fuel processing or fuel cell system.

The femur component of claim 1, wherein the dorsal indentation decreases in concave indentation from the proximal end to the tip.3. The femur component of claim 1, wherein the proximal end has an outer surface at its proximal end that is parabolic on the dorsal side and on a ventral side of the stem.4. The femur component of claim 3, wherein the medial portion has an outer surface that is concave along a medial contour, and that the outer surface center of curvature is medial and has a radius that decreases continuously in the proximal direction to form a parabolic shape.5. The femur component of claim 4, wherein the stem has a lateral outer surface that is substantially straight and partially circular in cross section.6. The femur component of claim 1, wherein the stem proximal end has an outer surface formed in the shape of a parabola on the dorsal side, on a medial side, and on a ventral side.7. The femur component of claim 1, wherein the proximal end of the stem has a ventral surface that is axially convex, and on the ventral side has a concave curvature that is substantially parabolic. that is structured and arranged for connection to the pulmonary veins of the mammalian body.9. The artificial lung device according to claim 8, wherein the second effluent duct has a check valve.10. The artificial lung device according to claim 8, wherein two artificial lung devices are used in parallel.
