Patent number: 8883117Abstract: A method of forming a material for reversible hydrogen storage within a storage tank includes charging a mixture of a metal amide and a metal hydride to the storage tank, and chemically reacting the mixture at a reaction condition within the storage tank to form a thermally conducting composite material situated in the storage tank and for reversibly storing hydrogen. The composite material includes a three-dimensional and interconnected framework including a conductive metal. A method for reversibly storing hydrogen includes providing a storage tank and in situ chemically forming a composite material by charging a mixture of a metal amide and a metal hydride to the storage tank and chemically reacting the mixture at a reaction condition to form a thermally conducting composite material including a metal hydride and a substantially unreactive elemental metal framework. Hydrogen is absorbed into the composite material and is desorbed from the composite material.Type: GrantFiled: March 26, 2013Date of Patent: November 11, 2014Assignee: Ford Global Technologies, LLCInventors: Jun Yang, Donald J.

Publication number: 20100068134Abstract: Methods of enhancing the kinetic properties of solid-state hydrogen storage materials are disclosed. The methods of the present invention comprise a process of utilizing built-in, ancillary reactions to effectually catalyze primary hydrogen storage reactions. This self-catalysis process gives rise to novel mechanisms for solid-state hydrogen storage compositions that benefit from enhanced kinetic properties, thereby increasing the usefulness of hydrogen storage technologies. The methods of enhancing the kinetic properties of hydrogen storage compositions by implementing a self-catalyzing reaction mechanism generally include formulating a hydrogen desorption pathway in a hydrogen storage composition, the pathway including a hydrogen releasing reaction and an ancillary reaction; and selecting the ancillary reaction to produce a product that serves to enhance the kinetic properties of the hydrogen releasing reaction.Type: ApplicationFiled: September 18, 2008Publication date: March 18, 2010Applicant: Ford Global Technologies, LLCInventors: Andrea Sudik, Jun Yang, Donald J.

Patent number: 6858103Abstract: The present invention discloses a method for optimizing heat treatment of precipitation-hardened alloys having at least one precipitate phase by decreasing aging time and/or aging temperature using thermal growth predictions based on a quantitative model. The method includes predicting three values: a volume change in the precipitation-hardened alloy due to transformations in at least one precipitation phase, an equilibrium phase fraction of at least one precipitation phase, and a kinetic growth coefficient of at least one precipitation phase. Based on these three values and a thermal growth model, the method predicts thermal growth in a precipitation-hardened alloy. The thermal growth model is particularly suitable for Al—Si—Cu alloys used in aluminum alloy components. The present invention also discloses a method to predict heat treatment aging time and temperature necessary for dimensional stability without the need for inexact and costly trial and error measurements.Type: GrantFiled: May 20, 2002Date of Patent: February 22, 2005Assignee: Ford Global Technologies, LLCInventors: Christopher Mark Wolverton, John Edmond Allison
