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.

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.

A child-resistant lighter is disclosed which includes an actuator and a latch member coupled thereto. The latch member includes a finger actuation portion and a body portion integrally formed therewith. The body portion has a free end. In accordance with one embodiment of the invention when in an inoperative position, the free end of the latch member is aligned with a blocking surface of the lighter body, thus, preventing inadvertent lighting of the lighter. When in an operative position, the free end of the latch member is pivoted out of alignment with the blocking surface so that the lighter can function. During pivoting, as the finger actuation portion moves in a first direction, the free end moves in an opposite, second direction. The first direction is substantially forward and the second direction is substantially rearward. In another embodiment, the latch member can be slidable coupled to the actuator. In another embodiment of the invention, the latch member includes the body portion and a cam member slidable coupled to the body portion. In yet another embodiment, a pulp portion of the user's finger is used to cause movement of the latch member from the locked position to the unlocked position and movement of the actuator from the first position to the actuation position.

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 present invention is also directed to system architecture for a fuel cell system that utilizes information storage devices.

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.

The present invention is directed to a fuel supply with an environmentally sensitive valve. The environmentally sensitive valve is sensitive to the environmental factor(s) such as temperature, pressure or velocity. The valve may be configured so that the valve automatically resets when the environmental triggering event no longer exists.

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.
