摘要：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 ofetchant is used to selectively remove material from the membrane's surface. Methodsfor repairing holes or other defects in the membrane are also disclosed. The inventionalso includes a membrane module adapted for use in purifying hydrogen streams, such asthose produced by fuel processors.
