| 20080216906 | Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus ( | 09-11-2008 |
| 20080226965 | Fuel Supply Systems Having Operational Resistance - A fuel supply ( | 09-18-2008 |
| 20080231836 | Fuel Cell with Fuel Monitoring System and Method of Use - A fuel cell ( | 09-25-2008 |
| 20090130507 | Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus includes a reaction chamber having a first reactant, a reservoir having an optional second reactant, and a self-regulated flow control device. The self-regulated flow control device stops the flow of reactant from the reservoir to the reaction chamber when the pressure of the reaction chamber reaches a predetermined level. Methods of operating the gas-generated apparatus and the self-regulated flow control device, including the cycling of a shut-off valve of the gas-generated apparatus and the cycling of the self-regulated flow control device are also described. | 05-21-2009 |
| 20090205727 | Fuel Cartridge with Connecting Valve - A shut-off valve or connecting valve capable of connecting a fuel supply to a fuel cell is disclosed. The valve comprises a first valve component and a second valve component. Each valve component has an outer housing and a biased slidable member disposed inside the housing forming an internal seal. During the connection process, the two valve components establish an inter-component seal. Afterward, in one suitable embodiment the slidable member moves inward and opens the internal seal in the valve component to establish a flow path. In another embodiment, the slidable member moves inward and exposes a first filler and the first filler abuts a second filler in the other valve component to establish a flow path. In other embodiments, at least one valve component is sized and dimensioned to limit access to the internal seal. | 08-20-2009 |
| 20100028748 | Device for Refilling a Fuel Cartridge for a Fuel Cell - A refillable fuel supply assembly for a fuel cell is disclosed herein. The assembly includes a refillable fuel supply adapted to supply fuel to a fuel cell, a refilling fuel cartridge containing fuel to be transferred to the refillable fuel supply, and a lock-and-release device connecting the refilling fuel cartridge to the refillable fuel supply to transport fuel from the refilling fuel cartridge to the refillable fuel supply. The lock-and-release device also retains the refilling fuel cartridge to the refillable fuel supply until the refilling fuel cartridge is substantially free of fuel. | 02-04-2010 |
| 20100099009 | VALVES FOR FUEL CARTRIDGES - Valves for connecting fuel supplies are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any fuel cells. The valves may include valves that vent gas from the cartridge and allow byproducts produced by the fuel cell to be transported to the fuel cartridge, and valves that connect the fuel supplies to the fuel cells | 04-22-2010 |
| 20100112400 | Fuel Cell Supply Including Information Storage Device and Control System - The present invention is directed to a fuel cell system with various features for optimal operations of an electronic device, a battery charger or a fuel refilling device. The fuel cell system includes an information storage device associated with the fuel supply, pump and/or refilling device. The information storage device can be any electronic storage device including, but not limited to, an EEPROM or a PLA. The information storage device can include encrypted information. The information storage device can include software code for confirming the identification of the cartridge before operation of the electronic device and/or refilling device. The information storage device can include instructions for a hot swap operation to shut down properly when the fuel supply is ejected while the electronic device is in operation. The present invention is also directed to system architecture for a fuel cell system that utilizes information storage devices. The system architecture may have flow regulators, which include a regulating valve. | 05-06-2010 |
| 20100151361 | Fuel Cartridges for Fuel Cells and Methods for Making Same - Fuel supplies for fuel cells are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any fuel cells, including but not limited to, direct methanol fuel cell or reformer fuel cell. In one aspect, a fuel supply may contain a reaction chamber to convert fuel to hydrogen. The fuel supplies may also contain a pump. The fuel supply may have a valve connecting the fuel to the fuel cell, and a vent to vent gas from the fuel supply. Methods for forming various fuel supplies are also disclosed. | 06-17-2010 |
