A fuel supply connectable to a fuel cell is disclosed. The fuel supply comprises an outer casing and a fuel liner and an effective amount of fuel in the space between the outer casing and the fuel liner to control the pressure inside the fuel liner. In one example, the fuel inside the fuel liner is methanol, and the fuel between the outer casing and the fuel liner is methanol or methanol gel.

The present invention relates to a lighter which a user actuates by at least two different modes of operation. In the first mode, a plunger member is positioned to allow a biasing member to oppose movement of an actuating assembly so that a user releases fuel and ignites the lighter only if a high-actuation-force is applied to the actuator. In this first mode, the lighter resists operation by unintended users by requiring a user to have a predetermined level of strength to actuate the lighter. In the second mode, the plunger member is moved to a different position so that the biasing member does not oppose movement of the actuating assembly to the same extent as the first mode so that a user may release fuel and ignite the lighter if a low-actuation-force is applied to the actuator. Moving the plunger member from the first position to the second position preferably requires the user to have a predetermined level of cognitive abilities and/or physical characteristics in order to resist use by unintended users. The lighter further includes a pivotal wand assembly. The wand assembly is operatively associated with a cam follower to allow only partial depression of an actuator when the wand assembly is in a closed position. Full depression of the actuator increases difficulty when the wand assembly is partially or fully extended.

The present invention is directed to a fuel cell supply for a fuel cell having an outer casing, a liner member containing methanol, and a valve component comprising a valve body member and a slidable body member disposed inside the valve body member. The slidable body member is normally biased toward a valve seat surface to seal the valve component and the slidable body member can be moved away from the valve seat surface to open the valve component. The liner member, the valve body member and the slidable body member are made from at least two different materials and wherein at least one of the members compatible with methanol. Hence, each component can be selected from material(s) that is substantially optimal for its function in the fuel supply.

A cartridge connectable to a fuel cell is disclosed. The cartridge comprises an outer casing and an inner flexible liner containing fuel for the fuel cell. The inner flexible liner may have an insert disposed inside the inner liner to facilitate the transport of fuel from the cartridge to the fuel cell. The insert minimizes the fuel that is trapped within the cartridge. The inner flexible liner can be used without the outer casing. The outer casing can be substantially rigid or flexible. The cartridge is also adaptable to receive byproducts from the fuel cell. The cartridge can also be pressurized to push fuel to the fuel cell. Unidirectional relief valves are also disclosed to prevent internal pressure in the cartridge from becoming too high or too low.

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.

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.

The present invention is directed to a fuel cell system with various features for optimal operations of an electronic device. The fuel cell system includes a fuel cartridge with a fuel reservoir containing fuel and a membrane electrode assembly (MEA) or a stack. The fuel cartridge is selectively operatively associated with the electronic device to power the device. In one embodiment, the fuel cartridge may be received within a chamber in the electronic device. In another embodiment, the fuel cartridge may be operatively associated with the electronic device while external thereto.
