NOVELTY - The membrane has a palladium alloy layer (16) permeable to atomic hydrogen at an operating temperature and including catalytic ability to disassociate molecular hydrogen into atomic hydrogen at an interface surface (18). A complex particles containing layer (20) includes a hydrogen impermeable material and a hydrogen permeable metal. The hydrogen permeable metal is selected from a group of vanadium, niobium and tantalum. The particles containing layer has another catalytic ability for disassociating molecular hydrogen into atomic hydrogen at an exposed surface.    USE - Hydrogen super-permeable membrane for separating pure hydrogen gas from a mixed gas source at a predefined operating temperature, for fueling a proton exchange fuel cell.    ADVANTAGE - The membrane is easily fabricated using different hydrogen permeable metals, without the need for a substrate. The membrane has the palladium alloy layer and the complex particles containing layer that are prevented from interdiffusing by using the complex particles that are too complex to diffuse. The membrane has a buckyball layer acting as a barrier layer that prevents inter-migration of the palladium alloy layer and a solid layer. The buckyball layer remains highly pervious to atomic hydrogen such that atomic hydrogen can freely pass through the membrane, due to structure of buckyballs in the buckyball layer.    DETAILED DESCRIPTION - The complex particles containing layer has complex particles that are selected from a group of stainless steel particles, ceramic particles, carbon buckytubes and carbon buckyballs. An INDEPENDENT CLAIM is also included for a method for fabricating a hydrogen separation membrane.
