Uitra-fure tydrogen a required in applications ranging from the manufacturing of semiconductors to powering fuel cells. The crystalline structure of palladium allows only the trasfer of atomic tydrogen (H) through its thickness and therefore palladium membranes are used to fiter hydrosen from contaminated sureams containine mbqures of hydrosen and other pases . Hydrosen molecules (Hy l are first odsorbed onto the polladlumis surlace and are then dissociated into atoms (H), which wubsequently oimise through the metal. The H atoens recombine on the opposite side of the membrane forming pure.H.
