    Abstract: An H 2 -permeable membrane system (117) comprises an electroless-deposited plating (115) of Pd or Pd alloy on a porous support (110, 110'). The Pd plating comprises face-centered cubic crystals cumulatively having a morphology of hexagonal platelets. The permeability to H 2 of the membrane plating (115) on the porous support is significantly enhanced, being at least greater than about 1.3x10 -8 mol.m -1 .s -1 .Pa -0.5 at 350 °C, and even greater than about 3.4x10 -8 mol.m -1 .s -1 .Pa -0.5 . The porous support (110, 110') may be stainless steel (1100 and include a thin ceramic interlayer (110') on which the Pd is plated. The method of providing the electroless-deposited plating includes preheating a Pd electroless plating solution to near a plating temperature substantially greater than room temperature, e.g. 60 °C, prior to plating.

    Abstract: A fuel processing system (14) supplies a flow of H 2 -rich reformate (60) to a water gas shift membrane reactor (62) having a water gas shift reaction region (74) and a permeate region (76) separated by an H 2 -separation membrane (64) . H 2 formed over a catalyst (75) in the reaction region selectively passes through the membrane to the permeate region for delivery to a use point, as the fuel cell (12) of a fuel cell power plant (10). A sweep gas (78), preferably steam (80), sweeps the permeate region to remove the H 2 therefrom and thereby facilitate further reaction and separation of H 2 . The direction of sweep gas flow relative to the reformate flow is controlled for H 2 -separation performance and is used to determine the loading of catalyst in the reaction region. The coolant (16, 16', 16"), thermal (40, 70A/70B), and/or pressure control (53, 55) sub-systems of a fuel cell power plant are integrated with the fuel processing system in a manner to provide increased system efficiency.
