Patent number: 9985306Abstract: The present application is directed to a gas-generating apparatus (10). Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The generation of hydrogen is regulated automatically by the selective exposure of a catalyst (48) to the fuel mixture depending on the pressure inside the reaction chamber (28) of the gas-generating apparatus. Catalyst sealing mechanisms (40, 42) are provided at least partially within the reaction chamber to regulate the hydrogen pressure and to minimize the fluctuations in pressure of the hydrogen received by the fuel cell.Type: GrantFiled: December 3, 2015Date of Patent: May 29, 2018Assignee: Intelligent Energy LimitedInventors: Alain Rosenzweig, Andrew J. Curello, Paul Spahr, Michael R. Curello

Patent number: 9722268Abstract: The present application is directed to gas generators comprising a fuel mixture and a catalyst. The catalyst is contained in a self-regulated reactor or buoy, and selectively opens and closes to produce a gas in accordance with the demand for gas. This fuel mixture is generally a solution formed by dissolving a solid fuel component in a liquid fuel component. The mixing preferably occurs before the first use, and more preferably occurs immediately prior to the first use. The inventive gas generators preferably further comprises a starting mechanism that isolates the solid fuel from the liquid fuel or vice versa before the first use. In one embodiment, the starting mechanism further comprises a catalyst shield mechanism that isolates the catalyst in the reactor or buoy from the liquid and/or the solid fuel prior to the first use.Type: GrantFiled: February 5, 2015Date of Patent: August 1, 2017Assignees: Intelligent Energy Limited, The Commissariat a L'energie Atomique et Aux Energies AlternativesInventors: Alain Rosenzweig, Andrew J.

Patent number: 9711809Abstract: The disclosure teaches controlling the fluid flow and pressure, including adjustable pressure regulators, pressure regulators with an inlet restrictor, semi-automatic valve and pressure regulator with a by-pass valve which use one or more of movable shuttle, shuttle housing, a high pressure diaphragm, a low pressure diaphragm and a fluidic conduit connecting the inlet to the outlet. One or more of these implementations adjust to modify the outlet pressure of the regulator. The inlet restrictor allows incoming fluid to enter the pressure regulators when the pressure of the incoming fluid is higher than a threshold level. The semi-automatic valve is opened manually but closes automatically when fluid flowing through the valve is insufficient to keep the valve open. The semi-automatic valve can also be a semi-automatic electrical switch. The by-pass valve directs the flow to bypass the pressure regulator, when the flow is slow or has low pressure.Type: GrantFiled: March 9, 2016Date of Patent: July 18, 2017Assignee: Intelligent Energy LimitedInventors: Andrew J. Curello, Paul Spahr, Kurt Rath

Patent number: 9016319Abstract: A compact, reliable, and easily manufacture relief valve capable of resolving pressure issues within a fuel cell system and its components or devices. The relief valve comprises a valve body having a first cap, a valve housing and a center post; and an elastomeric member or sealing member contained within the valve body and being secured to the valve body at one end and forming a seal with the valve body at the other end. The seal opens in response to a threshold pressure being exceeded. In one embodiment, the elastomeric member is secured to the interior of the first cap and/or valve housing and forms a seal with the outer diameter of the center post. The elastomeric member may be supported by a reinforcing member.Type: GrantFiled: October 26, 2010Date of Patent: April 28, 2015Assignees: Societe Bic, The Commissariat a l'Energie Atomique et aux Energies Alternatives (CEA)Inventor: Paul Spahr

Patent number: 8951310Abstract: Disclosed herein are multiple embodiments of a hydrogen generator (10) that measures, transports or stores a single dose of a viscous fuel component from first fuel chamber (12) in storage area (38) when the internal hydrogen pressure (44, 44?) of the hydrogen generator is high, and transports this single dose to a metal hydride fuel component in second fuel chamber (14) when the internal pressure is low, so that the viscous liquid and metal hydride fuel components react together to generate more hydrogen and to restart the cycle. The viscous fuel component can be water or alcohol, such as methanol, in liquid or gel form, and the metal hydride fuel component can be sodium borohydride or other metal hydride that chemically reacts with the viscous fuel to produce hydrogen. The metal hydride fuel component can be in solid or viscous form, e.g., aqueous form.Type: GrantFiled: February 1, 2008Date of Patent: February 10, 2015Assignee: Societe BICInventors: Andrew J.

Patent number: 8932777Abstract: Disclosed herein is a fuel supply comprising a compressed gas chamber and liquid fuel chamber. A pressure regulator connects the compressed gas chamber to the liquid fuel chamber. The pressure regulator is capable of taking a high pressure input from the compressed gas chamber and providing a substantially constant lower output pressure to the liquid fuel chamber. The pressure of the compressed gas chamber can decrease over time, but the pressure that urges liquid fuel out of the liquid fuel chamber remains substantially at the same level.Type: GrantFiled: August 21, 2008Date of Patent: January 13, 2015Assignee: Société BICInventors: Andrew J. Curello, Paul Spahr
