abstract = "Metal membranes based on highly permeable metals such as vanadium may be used to purify hydrogen for use in fuel cells, compound semiconductor manufacturing, or the chemical industry. Foils of V-Cu coated with thin films of palladium or palladium alloy were fabricated and tested for hydrogen permeability and stability during operation at temperatures from 320-450°C. The vanadium alloy foils (∼75 microns thick) were ionmilled and palladium coatings between 50 and 200 nm thick were applied to both sides in-situ, via electron beam evaporation PVD. The membranes were completely permselective for hydrogen. The rate of hydrogen flux decline at 400°C was gradual but accelerated quickly at higher temperatures. Hydrogen flux decrease was caused by metallic interdiffusion between the palladium coating and the vanadium alloy foil. Interdiffusion between various surface coatings and foils tested at different temperatures was characterized with AES depth profiles and RBS.",
