Hydrogen purification and storage system
Patent
·
OSTI ID:6526467
A hydrogen purification and storage system includes a hydride container holding hydride forming material adapted to adsorb hydrogen and gaseous impurities exposed to the material. A mixture of hydrogen and impurities is applied under pressure to the hydride container and there adsorbed by the hydride forming material. Application of a cooling fluid to the container into proximity with the hydride forming material facilitates the adsorption of hydrogen and impurities by the material. After adsorption of the hydrogen and impurities, the temperature of the hydride forming material in the container is increased to a point where hydrogen will be released from the material, but where the impurities will generally not be released. The hydrogen so released is then conveyed to a hydrogen utilization unit connected in the series with the container. After conveyance of the hydrogen to the utilization unit, the hydride forming material in the container is heated to a temperature greater than the first temperature to cause the impurities adsorbed by the material to be released; and these impurities are then conveyed from the container. This process may be repeated, as desired, to successively produce substantially pure hydrogen.
