The methods of purifying hydrogen isotopes from impurity gases to get ultra high pure (99 9999%) hydrogen gases were summarized, which advantages and disadvantages were also reviewed. The development and investigation of solid state diffusion membranes based on rare noble metal (alloy) palladium silver alloy were introduced emphatically. The merits and demerits of current employed Pd Ag alloy membranes were analyzed. It was pointed out that in order to prepare high selective hydrogen permeable membranes to get ultra high pure hydrogen, the surfaces of the refractory metals such as zirconium, niobium, tantalum and vanadium were modified, which utilized these metals/ high selective H permeability, and combined noble metal palladium/ catalytic activity for hydrogen and oxidation resistance, and then a high selective hydrogen permeable composite membranes was prepared. It could be indicated that this high selective hydrogen permeable membranes prepared by such technology are vastly applicable for producing ultra high pure hydrogen gases.
