Patent number: 9845239Abstract: Systems, devices, and methods combine thermally stable reactant materials and aqueous solutions to generate hydrogen and a non-toxic liquid by-product. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Springs and other pressurization mechanisms pressurize and deliver an aqueous solution to the reaction. A check valve and other pressure regulation mechanisms regulate the pressure of the aqueous solution delivered to the reactant fuel material in the reactor based upon characteristics of the pressurization mechanisms and can regulate the pressure of the delivered aqueous solution as a steady decay associated with the pressurization force.Type: GrantFiled: July 1, 2015Date of Patent: December 19, 2017Assignee: Intelligent Energy LimitedInventors: Andrew P. Wallace, John M. Melack, Michael Lefenfeld

Patent number: 9669371Abstract: Systems, devices, and methods combine reactant materials and aqueous solutions to generate hydrogen. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Multiple inlets of varied placement geometries deliver aqueous solution to the reaction. The reactant materials and aqueous solution are churned to control the state of the reaction. The aqueous solution can be recycled and returned to the reaction. One system operates over a range of temperatures and pressures and includes a hydrogen separator, a heat removal mechanism, and state of reaction control devices. The systems, devices, and methods of generating hydrogen provide thermally stable solids, near-instant reaction with the aqueous solutions, and a non-toxic liquid by-product.Type: GrantFiled: June 8, 2015Date of Patent: June 6, 2017Assignee: Intelligent Energy LimitedInventors: Andrew P.

Publication number: 20150376002Abstract: A water reactive hydrogen generation system includes devices and methods to combine reactant fuel materials and aqueous solutions to generate hydrogen. The generated hydrogen is used in a fuel cell or other application. The water reactive hydrogen generation system includes a reactant fuel chamber, a reactor chamber (zone), a water solution inlet, a hydrogen output port, and a material delivery device. The material delivery device can include a drive screw and a sliding piston to move the fuel material into the reactor zone when a reaction is initiated. As the reaction takes place, the reaction waste product is removed from the reaction zone to allow additional reactant fuel materials and aqueous solutions to be introduced and to continue the hydrogen-generating reaction. A reaction waste product created is exchanged for additional reactant fuel material at determined intervals to allow the reaction to continue until the reactant fuel is exhausted.Type: ApplicationFiled: September 3, 2015Publication date: December 31, 2015Applicant: Intelligent Energy LimitedInventors: Andrew P.
