摘要:
Practice of this invention provides, at least, a method of making a hydrogen storage material comprising the steps of: 1. forming a molten mixture comprising nickel and at least one other transition metal element, the combination of which will form a TiNi alloy and including in said molten mixture from about 0.1 at. % to about 10 at. % of one or more elements which will form an alloy which is immiscible in the TiNi-type alloy; and (b) cooling said molten mixture to form a solid alloy-system material by rapid solidification of said molten mixture at a cooling rate of at least 103° C. per second.

摘要:
A fundamentally new magnesium-based hydrogen storage alloy material which makes it feasible and practical to use solid state storage and delivery of hydrogen to power internal combustion engine or fuel cell vehicles. These alloys have remarkable hydrogen storage capacity of well over 6 weight percent. The alloys also have extraordinary absorption kinetics such that the alloy absorbs 80 percent of its total capacity within five minutes. The alloys are in particle form where the particles have a size ranging from 30 to 70 microns. The alloys also have a dual phase structure (formed by cooling from the melt at a cooling rate of 103-104° C.). The dual phase structure is such that an intergranular region surrounds a major hydrogen storage phase thus providing the alloys with resistance to sintering during high temperature hydriding/dehydriding cycling thereof. As a result of the dual phase structure, the alloys have an extended cycle life.

摘要:
An onboard hydrogen storage unit with heat transfer system for a hydrogen powered vehicle. The system includes a hydrogen storage vessel containing a hydrogen storage alloy configured to receive a stream of hydrogen and provide hydrogen for use in powering a vehicle. During refueling a cooling/heating loop is used to remove the heat of hydride formation from the hydrogen storage alloy and during operation of the vehicle the heating/cooling loop is used to supply heat to the hydrogen storage alloy to aid in hydrogen desorption.
