    Abstract: This invention is a method for improving the electrical properties of silicon semiconductor material. The method comprises irradiating a selected surface layer of the semiconductor material with high-power laser pulses characterized by a special combination of wavelength, energy level, and duration. The combination effects melting of the layer without degrading electrical properties, such as minority-carrier diffusion length. The method is applicable to improving the electrical properties of n- and p-type silicon which is to be doped to form an electrical junction therein. Another important application of the method is the virtually complete removal of doping-induced defects from ion-implanted or diffusion-doped silicon substrates.

    Abstract: Hydrogen propelled fuel cell vehicle system designs that reduce the relative cost of releasing hydrogen from hydrogen storage alloys by providing and/or utilizing secondary sources of heat to supply the heat of desorption of stored hydrogen. The secondary source can include combusting conventional secondary (non-hydrogen) fuels. The fuel supply system uses fundamentally new magnesium-based hydrogen storage alloy materials which for the first time make it feasible and practical to use solid state storage and delivery of hydrogen to power fuel cell vehicles. These exceptional alloys have remarkable hydrogen storage capacity of over 7 weight % coupled with extraordinary absorption kinetics such that the alloy powder absorbs 80% of its total capacity within 1.5 minutes at 300° C. and a cycle life of at least 2000 cycles without loss of capacity or kinetics.

    Abstract: A hydrogen cooled hydrogen storage unit which employs excess hydrogen flow through flow channels between hydrogen storage alloy plates in order to provide convective cooling of the plates. The unit provides for high packing density of the storage materials and ease of expansion of storage capacity by merely adding more storage material plates. Since the hydrogen flows transversely between the plates and does not flow along the entire length of the stack, the cooling flow path of the hydrogen is short, and the temperature differential between any point of the stack and the hydrogen coolant is maximized, which maximizes the cooling efficiency of the unit.
