Abstract

A dense hydrogen-permeable layer, such as palladium or palladium alloy, is deposited on a porous hollow fiber. A porous hollow fiber is defined as having an inner diameter of approximately 30 microns to approximately 1500 microns and an outer diameter of approximately 100 microns to approximately 2000 microns. This allows an order-of-magnitude increase in the surface per volume ratio in a hydrogen separation or purification module, or a membrane reformer or reactor.
