Abstract
A hydrogen permeation membrane is provided having a cP2 Pearson symbol (Pm3m space group) structure. Suitable alloys include an 'A' element from Periodic Table groups 3b-5b and an 'M' element from the Periodic Table groups 6b-1b present at a stoichiometry that achieves the inventive crystal structure. Zr and Nb are the preferred A elements followed in preference by Ti and V. First Periodic Table row elements from groups 6b-1b are the preferred B elements. The inventive alloys also find applications as hydrogen getters, Ni-metal hydride battery materials, and hydrogen storage materials.
