Abstract
An H-permeable membrane system () comprises an electroless-deposited plating () of Pd or Pd alloy on a porous support (). The Pd plating comprises face-centered cubic crystals cumulatively having a morphology of hexagonal platelets. The permeability to Hof the membrane plating () on the porous support is significantly enhanced, being at least greater than about 1.3×10mol·m·s·Paat 350° C., and even greater than about 3.4×10mol·m·s·Pa. The porous support () may be stainless steel (and include a thin ceramic interlayer () 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.
