Specific permeabilities and diffusion constants for H have been measured in a series of Pd-Al alloy membranes using a new method for activation of the membranes. The membranes have been partially internally oxidized at an elevated temperature before inserting into the apparatus for measuring H2 permeabilities. It has been observed that the kinetics of H2 absorption are faster for internally oxidized Pd-Al alloys than for pure Pd foil [1] and, in addition, the partially internally oxidized alloys offer a greater resistance to poisoning by CO(g) [2].
