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.

Fuel cell supply including information storage device and control system

The present application is directed to a gas-generating apparatus (). 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 () to the fuel mixture depending on the pressure inside the reaction chamber () of the gas-generating apparatus. Catalyst sealing mechanisms () 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.

Hydrogen-generating fuel cell cartridges

The present invention relates to a connector or cable between the fuel supply and the fuel cell that in addition to transporting fuel and electrical power can also communicate control signals between the fuel cell and the cartridge to instruct the fuel cartridge or the fuel cell or both to commence or cease the operation of one or more functions. Control signals can be electrical, fluidic/hydraulic and/or mechanical. The connector or cable may also transport electricity produced by the fuel cell to power an electronic device, and/or to the fuel cartridge to power a component(s) on the cartridge or to re-charge a battery. The connector or cable may have universal connectors that can attach to multiple fuel cells, fuel cartridges and electronic devices, even when manufactured by different manufacturers.

Multi-functional fuel cable

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.

Gas generator with starter mechanism and catalyst shield

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.

Fluidic components suitable for fuel cell systems including pressure regulators and valves

The present application is directed to a hydrophobic membrane assembly () used within a gas-generating apparatus. Hydrogen is separated from the reaction solution by passing through a hydrophobic membrane assembly () having a hydrophobic lattice like member () disposed within a hydrogen output composite () further enhancing the ability of the hydrogen output composite's ability to separate out hydrogen gas and prolonging its useful life.

Hydrogen membrane separator

A fuel supply () is attachable to a fuel cell system (). The fuel supply includes a fuel supply connector () configured to be attached to the fuel cell system. A fuel supply connector automatically separates the fuel supply from the fuel cell system in a predetermined manner if exposed to a separation load. Valves () or filler material (-) are used to automatically stop the flow of fuel through the fuel supply connector. Alternatively, the fuel supply connector includes a flexible tube () and a valve disposed within the connector. The flexibility of the tube prevents the connector from breaking in case of a separation load.

Separable fuel cartridge

Fuel supplies including multiple valve components and fuel cell systems having increased operational resistance to the insertion and/or removal of fuel supplies are disclosed. The increased operational resistance is provided by increased insertion or removal forces, multiple relative motions for insertion and/or removal, latches, actuators, ON/OFF switches, cognitive ability of the user, visual alignment, audio feedback, size of the user's hand, inter alia.

Fuel supply systems having operational resistance

The present application is directed to a gas-generating apparatus and various pressure regulators or pressure-regulating valves. Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The transportation of a first fuel component to a second fuel component to generate of hydrogen occurs automatically depending on the pressure of a reaction chamber within the gas-generating apparatus. The pressure regulators and flow orifices are provided to regulate the hydrogen pressure and to minimize the fluctuation in pressure of the hydrogen received by the fuel cell. Connecting valves to connect the gas-generating apparatus to the fuel cell are also provided.

The present invention is directed to devices for 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. The adjustable pressure regulators have a 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 components are adjusted 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 positioning the inlet restrictor can be used to prevent a partial vacuum from forming inside a pressure regulator. 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.

A fuel cell system () with a toggle switch () between an ON or OFF position is provided. In the OFF position, gas is purged from the fuel cell. The fuel cell () may surround the fuel source () with the cathode side of the fuel cell facing the fuel source. Additionally, both the fuel cell () and the fuel source () may have similar form factor to maximize the available space. Preferably the form factor is substantially an oval shape. The fuel cell system may also have a pressure regulator ().

Fuel cell system having a toggle switch

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.
