    Abstract: A system and method of efficiently producing ultrapure hydrogen from ammonia using a single energy efficient processing step. Ammonia is introduced into reaction cells. Each reaction cell has a first tube of hydrogen permeable material that is concentrically positioned within a second tube of hydrogen impermeable material. The concentric orientation between the first tube and the second tube creates a very narrow reaction gap space between the two tubes. The reaction cell is heated to an operational temperature that is efficient for the heat cracking of ammonia and which makes the first tube highly permeable to hydrogen. Ammonia is introduced into the gap space, wherein the ammonia cracks into nitrogen and hydrogen. The hydrogen contacts the first tube and permeates through the first tube. Accordingly, the cracking of ammonia and the separation of hydrogen occurs in the same reaction cell at the same time using the same heat energy.

    Abstract: A system and method of producing hydrogen from a mixture of hydrocarbon fuel and steam. Reaction cells are provided that each contains a first tube of hydrogen permeable material and a second tube of hydrogen impermeable material that are concentrically positioned. This creates a gap space between the first tube and the second tube. The gap space is heated by burning a combustion gas outside of the two concentric tubes. A water gas shift reaction occurs in the gap space. Hydrogen is created that permeates through the first tube and becomes separated from the remainder of the reaction gases. The hydrogen gas is collected for use. As such, the system and method acts both as a gas shift reactor and as a hydrogen separator even though it is a single unit.

    Abstract: A system and method of taking a sample of hydrogen gas and reducing the hydrogen concentration by a factor greater than 1×108 while increasing the partial pressure of the contaminating gases by a factor greater than 100, so that extremely low levels of contamination can be accurately detected. A sample of hydrogen gas is captured. Only the hydrogen gas is removed leaving all the contaminating gases in the collection chamber. This causes the total pressure of the gas sample within the collection chamber to decrease dramatically since most of the gas was hydrogen. All the contaminants remain in the collection chamber. None are lost through pumping. As such, the concentration of contaminants within the remaining sample increases dramatically. The residual partial pressures of the contaminating gases within the collection chamber and can now be measured by a variety of techniques.

    Abstract: A steam reformer is use in a fuel processor system to create a water gas shift reaction between a hydrocarbon fuel and water. A hydrocarbon fuel and water are provided. The water is heated to superheated steam. The hydrocarbon fuel is mixed with the superheated steam to produce a vaporized fuel/steam mixture. The vaporized fuel/steam mixture is directed into a gap space between concentric tubes. The gap space between the separate surfaces is very small. Within this confined gap space, the outer concentric tube is heated to maintain a reaction temperature range that induces the water gas shift reaction. The water gas shift reaction produces reactant gases that include hydrogen gas and contaminant gases. At least some of the contaminant gases are burned to heat the gap space.

    Abstract: A system and method for converting the natural gas into liquid hydrocarbons. A plurality of reaction cells are provided. Each reaction cell contains two concentric tubes. The concentric tubes are close in diameter and therefore create a very narrow uniform gap space in between the concentric tubes. The outer most of the tubes is heated. Natural gas and steam are passed into the gap space of at least some of the reaction cells. Due to the confinement of the gases and the heat, the mixture undergoes a water gas shift reaction to produce syngas. The syngas can then be reintroduced into other reaction cells to induce the Fischer-Tropsch process. Accordingly, the syngas is converted into complex hydrocarbons and water. The hydrocarbons and water are separated and cooled into liquid. The water is recycled and the liquid hydrocarbons are stored and transported.

    Abstract: A hydrogen purification system and method that utilizes a hydrogen separator with a novel composite structure. The hydrogen separator has a first porous layer of a hydrogen permeable material. The first porous layer is comprised of premanufactured nano-particles of hydrogen permeable material that have been bonded together. A solid layer of the same hydrogen permeable material is then disposed onto the first porous layer. A pressure differential is created across the structure of the composite hydrogen separator. The porous layer of hydrogen permeable material supports the solid layer and enables the solid layer to withstand large pressure differentials. Furthermore, the porous layer of the hydrogen permeable material bonds to the solid layer, thereby greatly increasing the effective surface area of the solid layer that is exposed to hydrogen gas. Accordingly, a large flow rate of hydrogen gas can be obtained in a small amount of space.

    Abstract: A hydrogen diffusion cell that is used to purify contaminated hydrogen gas. The hydrogen diffusion cell has a supply tube that supplies contaminated hydrogen gas into a confined area and a drain tube that removes contaminated hydrogen gas from the confined area. Hydrogen permeable coils are disposed between the supply tube and the drain tube. The coils include at least one small diameter coil. Concentrically surrounding the small diameter coil is at least one larger diameter coil. All coils are mounted in such a manner so that they maintain a constant radius of curvature along their entire lengths.

    Abstract: A system and method of winding a length of tubing into a coil. The system uses a mandrel to wind a length of tubing into the form of a coil. The length of tubing is both internally pressurized and placed under tension prior to being wound around the mandrel. The tension experienced by the length of tubing causes the tubing to conform to the shape of the mandrel as the mandrel rotates. The internal pressurization of the tubing keeps the diameter of the tubing round as it is deformed around the mandrel. As such, the tubing is prevented from crushing or buckling as it winds around the mandrel.
