Appl. No.:

11/750246

Inventors:

DANIEL A. WATTS - Surfside CA, US
JASON A. GROW - Huntington Beach CA, US

Assignee:

THE BOEING COMPANY - Chicago IL

International Classification:

F17C 9/02
F17C 13/00

US Classification:

62 502, 62 501, 62 507, 62 56, 141 4

Abstract:

In one embodiment of the disclosure, an apparatus is provided for fueling a device using a cryogenic fluid. The apparatus may comprise: a cryogenic fluid supply container; a vessel connected to the supply container with an entrance valve to regulate flow of cryogenic fluid from the supply container; a heat transfer system capable of transferring heat from a device to the vessel to heat gas in the vessel; and an accumulator connected to the vessel with an exit valve to regulate flow of gas from the vessel to the accumulator. The accumulator may be capable of being connected to a device. In other embodiments, methods are provided of controllably mixing at least one fluid within a fluid mixing device.

International Classification:

F17C 13/00

US Classification:

62 506

Abstract:

A hydrogen pump comprises a pump housing and a heating mechanism. The pump housing receives liquid hydrogen through a housing inlet. The heating mechanism vaporizes the liquid hydrogen into gaseous hydrogen. The pump housing releases the gaseous hydrogen through a housing outlet at a predetermined pressure level of the gaseous hydrogen. The pump housing closes the housing outlet such as when the liquid hydrogen in the pump housing falls below a depletion level. The pump housing opens and additional liquid hydrogen enters the pump housing through the housing inlet.

International Classification:

F04B 19/24

US Classification:

417 53, 417208, 417209

Abstract:

A thermodynamic pump for provides gaseous hydrogen employing a plurality of liquid hydrogen (LH2) tanks sequentially pressurized with gaseous hydrogen (GH2) from an accumulator. A heat exchanger receiving LH2 from each of the plurality of tanks as sequentially pressurized returns pressurized GH2 to the accumulator for supply to an engine.

International Classification:

H01M 8/04

Abstract:

Technologies are described herein for conditioning fluids stored in an underwater cryogenic storage vessel designed for use in a fuel system of an underwater vehicle. According to one aspect of the disclosure, a fuel system includes a fuel cell and a storage vessel, which stores a first fluid that is supplied to the fuel cell and a second fluid that is produced by the fuel cell. The fuel system also includes a thermal conditioning module that receives the first fluid from the storage vessel and receives the second fluid from the fuel cell. The first fluid stored in the storage vessel is conditioned by absorbing heat from the second fluid, such that the fuel cell receives the conditioned first fluid. The second fluid received from the fuel cell is in gaseous state and is converted to a liquid. The liquid second fluid is stored in the storage vessel.
