ABSTRACT:
A hydrogen-permeable metal membrane with increased hydrogen flux compared to conventional metal membranes is disclosed. Without sacrificing selectivity, the membrane enables a greater throughput of purified hydrogen. A method for preparing the invention includes at least one etching step in which a controlled volume of etchant is used to selectively remove material from the membrane's surface. Methods for repairing holes or other defects in the membrane are also disclosed.
