Hydrogen transport membrane

Abstract

A hydrogen transport membrane in which a porous ceramic support supports a dense layer of palladium or an alloy of palladium serving as a hydrogen transport material. The ceramic support has a first porous layer and a second porous layer. The first porous layer has a first thickness of about 1 mm, a first set of pores have a first average pore size of between about 10 microns and about 50 microns and a first porosity of about 40 percent by volume. The second porous layer has a second thickness of about 3 microns, a second set of pores having a second average pore size of between about 10 nanometers and about 100 nanometers and a second porosity of about 50 percent by volume. The dense layer has a thickness of about 3 microns.
