Patent ID: 7727308

Claim:
A method for sorption of hydrogen, comprising contacting the hydrogen with a non-evaporable getter alloy having a composition, expressed in weight percent, of 50-80% Zr, 10-20% Y, and a remainder M 5-40%, wherein M is selected from the group consisting of Al, Fe, Cr, Mn, V and mixtures thereof, and when represented in a ternary diagram of weight percent, the composition falls within a polygon defined by the following points: a) Zr 50%-Y 10%-M 40% b) Zr 50%-Y 20%-M 30% c) Zr 75%-Y 20%-M 5% d) Zr 80%-Y 15%-M 5% e) Zr 80%-Y 10%-M 10%, wherein the alloy is present in a getter device and the getter alloy has a form of a powder, and wherein the getter device comprises pellets consisting essentially of compressed powders of the getter alloy.
