Abstract: The invention relates to a method and an apparatus for handling small quantities of fluids useful, for example, in measuring the gas and/or liquid sorption and desorption properties of substances such as hydrogen sorption by solid or liquid hydrogen storage materials. In one embodiment, low-volume rotary valves are used to dose samples in a sample holder. In another embodiment, a rotary valve is used as a dosing/bypass valve to both condition and measure samples. The invention also relates to an actuator for a rotary valve that has a manual override feature.

Abstract: Methods of forming materials that contain hydrogen storage materials and nano-structured matrices are described. In one embodiment, the hydrogen storage material is a complex hydride. In another embodiment, the method includes melting at least one compound capable of storing and releasing hydrogen, obtaining an aluminum-containing nano-structured matrix having a melting point higher than the temperature of the at least one compound, and contacting the molten at least one compound with the nano-structured matrix to facilitate the coating of the nano-structured material with the molten at least one compound. The matrix may undergo mechanical working to further modify the nano-structure. In yet another embodiment, the method includes forming a powder including a gas-atomized aluminum-containing powder, and pressing or sintering the powder to form a matrix, such that the matrix has nano-meter scale pores.

Abstract: In a method for approaching a moving article over an approach path, an approach position of the article is situated within an approach region, control data sets are calculated in advance in a first calculation step, the control data sets contain a movement set that includes path segments, which describe the approach path for an approach position, the first calculation step for the movement set is based on a first determined approach position of the article, the movement set for the first determined position of the article is optimized with regard to the approach speed, the current approach position of the article is determined immediately before the start of the movement, a second calculation step is carried out in which the respective path segment to be currently executed is changed as a function of the determined current approach position of the article so that the approach path is shifted in the direction of the current approach position, and an approach movement is carried out by executing the path segmen

Abstract: A method is described for the direct synthesis of reversible hydride materials by hydrogenating a mixture of aluminum, an alkali-metal hydride, and one or more of an alkali-metal amide or an alkali-metal imide, an alkaline-earth-metal or alkaline-earth-metal hydride, and a transition metal catalyst. In one embodiment, the mixture includes aluminum, LiH, LiNH2, magnesium, and TiF3 in the molar ratio of 1:1:2:1:0.05. The material is capable of being repeatedly hydrogenated and dehydrogenated. The method is likely capable of forming a variety of hydrogen storage materials that includes alanates and amides or imides, and which have high hydrogen storage capabilities without the use of ammonia. A method is also described of using two component hydrogen storage materials by segregating the material components.

Abstract: A method and apparatus are presented for controlling the flow of gas from a source to a low-pressure device which is particularly useful for sampling high pressure gases. Examples are presented for the high-pressure dosing of an RGA. In one embodiment, the method isolates volumes of gases at high pressure, limits their pressure, and provides the gas at low pressure. In one embodiment the apparatus includes valves, flow restriction devices, and check valves, and can be used, for example, to either provide accurate and repeatable quantities discrete doses of gas from high pressure to low pressure or provide continuous dosing from high to low pressure. The apparatus and method are relatively insensitive to source pressure, and thus provide reproducible results over a range of source pressures.

Abstract: Hydrogen is stored in materials that absorb and desorb hydrogen with temperature dependent rates. A housing is provided that allows for the storage of one or more types of hydrogen-storage materials in close thermal proximity to a fuel cell stack. This arrangement, which includes alternating fuel cell stack and hydrogen-storage units, allows for close thermal matching of the hydrogen storage material and the fuel cell stack. Also, the present invention allows for tailoring of the hydrogen delivery by mixing different materials in one unit. Thermal insulation alternatively allows for a highly efficient unit. Individual power modules including one fuel cell stack surrounded by a pair of hydrogen-storage units allows for distribution of power throughout a vehicle or other electric power consuming devices.
