Abstract
A hydrogen permeable membrane device is provided that includes a porous ceramic layer having a material that includes zirconia, Yttria-stabilized zirconia (YSZ), γ/Al2O3, and/or YSZ— γ/Al2O3, and a porous Pd film or porous Pd-alloy film deposited on the a mesoporous ceramic layer.
Claims14
A hydrogen permeable membrane, comprising:
- a) a porous support layer of metal, ceramic or a metal and ceramic with pore size in the range of 2 nm to 50000 nm;
- b) a hydrogen selective Pd 95-Ag5 film at a thickness in the range of 0.5 to 150 μm disposed onto the porous support layer;
- and
- c) a porous protective layer of 50% YSZ—50% γ-Al2O3 at a thickness in the range of 0.5 to 150 μm disposed onto the hydrogen selective Pd95-Ag5 film.
