Patent number: 8381766Abstract: Systems and methods are provided for hydrogen generation utilizing two or more liquid fuel components, using a fuel delivery system comprising a single reversible or bi-directional pump co-operable with flow control means comprising passive or active valves to deliver two or more fuel components to a mixing zone, reaction zone, or reaction chamber of a hydrogen generation system. The pump is operable in a forward direction to deliver one fuel component, and in a reverse direction to deliver a second fuel component. Control of the pump speed, direction and duty cycle of the pump in continuous or pulsed modes provides for delivery of first and second fuel components in desired proportions, to control hydrogen generation. The system also allows for dilution, mixing and flush cycles to be provided using a single pump, reducing the number of active elements required for fuel delivery and flow control in systems using two or more liquid fuel components.Type: GrantFiled: March 6, 2008Date of Patent: February 26, 2013Assignee: Protonex Technology CorporationInventors: Keith A.

The hydrogen generator comprises a fuel chamber for storing a solid chemical hydride, a chamber for storing a liquid reagent, and a liquid distributor disposed within the fuel chamber. The contact between the solid chemical hydride and the liquid reagent produces a substantially fluid nongaseous product and hydrogen gas. The liquid distributor is configured to move through at least a portion of the substantially fluid nongaseous product within the fuel chamber.Type: ApplicationFiled: October 18, 2007Publication date: April 23, 2009Inventors: Richard M.

Publication number: 20090047185Abstract: Systems and methods are provided for hydrogen generation utilizing two or more liquid fuel components, using a fuel delivery system comprising a single pump. Advantageously, a single reversible cycle pump is used to deliver two or more fuel components of a fuel mixture in desired proportions to a mixing zone, reaction zone, or reaction chamber of a hydrogen generation system, while reducing the number of active elements required for fuel delivery and flow control of multiple fuel components. Alternatively, a unidirectional single or duel feed pump co-operable with flow control means comprising a valve provides for delivering first and second fuel components in desired proportions. Control of the pump speed, and duty cycle of the pump in continuous or pulsed modes, provides for delivery of first and second fuel components in desired proportions, to control hydrogen generation, and to provide for dilution, mixing, and flush cycles, using a single pump.Type: ApplicationFiled: March 6, 2008Publication date: February 19, 2009Inventors: Keith A.

Publication number: 20070271844Abstract: Systems and methods are provided for generating hydrogen gas using a catalyst or reagent and a boron hydride compound. The preferred hydrogen generation system includes a fuel cartridge and a hydrogen generation system balance of plant (BOP) module. Solid fuel is stored in individual fuel packets in a fuel chamber, and converted into a fuel solution. Fuel is pumped to a reactor where it produces hydrogen and borate. The hydrogen and borate product exit the reactor and are deposited in a hydrogen separation chamber separated from the fuel chamber by a moveable partition. Hydrogen is separated by a membrane and exits the generator. As fuel is consumed, the movable partition is disposed toward the fuel chamber and the borate product is deposited on one side of the movable partition. The controls are preferably contained in the BOP module.Type: ApplicationFiled: April 12, 2007Publication date: November 29, 2007Inventors: Richard Mohring, Keith Fennimore
