SYSTEM AND METHOD FOR WELDING A PLURALITY OF SMALL DIAMETER PALLADIUM ALLOY TUBES TO A COMMON BASE PLATE IN A SPACE EFFICIENT MANNER
A number of assemblies are joined together into a matrix by a plate. The plate has a first surface, an opposite second surface and a plurality of holes. Each hole has a countersunk region that descends into the plate from the first surface. Tube assemblies are provided. Each tube assembly has a first end, an opposite second end, and a flare structure. The flare structure is sized to be fully received within the countersunk region. The tube assemblies extend through the holes in the plate. The flare structure of each tube assembly is welded to the plate within the countersunk region of each hole through which each tube assembly passes.
An apparatus for recycling exhaust gas includes a vessel (52) containing a reversible ammonia sorbing material (70) which is exothermic when sorbing ("loading") ammonia and which is endothermic when releasing ("unloading") ammonia. A first valve selectively couples a source of exhaust gas including ammonia to a first port (58) of the vessel, a second valve selectively couples a vacuum pump to the vessel, and a third valve selectively coupling a second port (62) of the vessel to an output. A controller opens and closes the first valve, the second valve and the third valve to implement a loading phase, an intermediate venting phase and an unloading phase for the vessel.
A tube matrix and the corresponding method of joining a plurality of tubes to a base plate to create the tube matrix. The tube matrix has a base plate from which a plurality of parallel tubes extend. The base plate has holes formed though it to receive the tubes. The tubes are placed into the holes on the base plate. The tubes may have end flares that abut against the base plate and prevent the tubes from completely passing through the base plate. Once the tubes are in place in the holes of the base plate, the tubes and base plate are welded together with individual laser welds. The laser welds enable a very dense matrix of tubes to be welded to the base plate without damaging or obstructing the tubes.

System and method for separating hydrogen gas from a mixed gas source using composite structure tubes
A hydrogen purification system that is used to separate hydrogen gas from a mixed gas source. The hydrogen purification system includes a hydrogen separator. Within the hydrogen separator is a first chamber into which the mixed gas source is fed. A plurality of tubes extend into the first chamber. Each of the plurality of tubes is permeable only to hydrogen. Gap spaces exist within the first chamber in between any of the plurality of tubes that are arranged in adjacent positions. The mixed source gas passes through the gap spaces as it permeates the first chamber. The mixed gas source spreads thinly over the exterior of the tubes within the confines of the gap spaces. Hydrogen from the mixed gas source permeates thru the tube walls and into the interior of the tubes that are in parallel and the hydrogen is collected in a chamber.

System and method for reducing thermal shock in a hydrogen diffusion cell
A system and method of purifying hydrogen gas. The system includes heating elements for heating the hydrogen diffusion cell to a predetermined operational temperature. A preheater is provided for heating unpurified gases that will enter the hydrogen diffusion cell. The unpurified gases are heated to the operational temperature of the hydrogen diffusion cell before entering the hydrogen diffusion cell. In this manner, the inflow of unpurified gases into the hydrogen diffusion cell does not cause any thermal shock to the hydrogen diffusion cell. The incoming unpurified gases are heated in two ways. The unpurified gases are heated in a preheater. The unpurified gases are also heated in a heat exchanger. The heat exchanger recycles the heat from the purified hydrogen gas.

Hydrogen gas separator system having a micro-channel construction for efficiently separating hydrogen gas from a mixed gas source
A hydrogen purification method that is used to separate hydrogen gas from a source gas. A hydrogen separator into which flows the source. Within the hydrogen separator is at least one hydrogen permeable tube that is made of a hydrogen permeable material. A support tube is provided for each hydrogen permeable tube. A support tube is coaxially aligned with the hydrogen permeable tube, wherein a micro-channel exists between the hydrogen permeable tube and the support tube in an area of overlap. The source gas is introduced into the micro-channel. The source gas spreads thinly over the hydrogen permeable tube in the micro-channel. The restrictions of the micro-channel cause the source gas to embody turbulent flow characteristics as it flows through the micro-channel. The turbulent flow causes the hydrogen separator to separate hydrogen from the source gas in a highly efficient manner.
