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.

Hydrogen propelled vehicles and 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 internal combustion engine or fuel cell vehicles. These exceptional alloys have remarkable hydrogen storage capacity of well over 6 weight % coupled with extraordinary absorption kinetics such that the alloy powder absorbs 80% of its total capacity within 10 minutes at 300&deg; C. and a cycle life of at least 500 cycles without loss of capacity or kinetics.

A low temperature hydrogen storage alloy which is not pyrophoric upon exposure to ambient atmosphere, particularly even after hydrogen charge/discharge cycling.

Non-pyrophoric hydrogen storage alloy

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 10  &deg; 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.

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.
