Summary: Palladium-alloy membranes that exhibit structural stability, improved strength, and
high hydrogen flux
Description:
The potential use of palladium (Pd) membranes for selective hydrogen
permeability has been recognized for decades. Yet, Pd-alloy membranes have not been
commercialized due to deficiencies in their long-term stability, high costs, and
manufacturability. This invention details a method to fabricate very thin, composite
membranes of Pd alloyed with Ru, Rh, and Pt that exhibit structural stability, improved strength
and high hydrogen flux at temperatures up to 600C. The membranes can be fabricated on
tubular porous substrates, which can be assembled into high surface area membrane modules.
Main Advantages of this Invention
 High strength and structural
stability
 High hydrogen flux
Potential Areas of Application
 Hydrocarbon reforming
 Hydrogen production
 Fuel cell
 Petrochemical refineries
