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.

In accordance with different embodiments of the present invention, duckbill check valve , having an orifice , and conical check valve , having an orifice , are responsive to the differential pressure of fluid F as it flows between inlet and outlet. In an innovative aspect of the invention, orifice and orifice each have a variable effective diameter. In one embodiment, the duckbill check valve and conical check valve have a conical end that is aligned with the direction of fluid flow. In another embodiment, the duckbill check valve can have a conical end that faces the direction of fluid flow. A pin may traverse orifice or.

A fuel supply () including a cover () having an opening () for access to the fuel. The cover () includes a shutter () or similar element for closing off the opening () to increase the operational resistance to the insertion and/or removal of the fuel supply (). In one embodiment, the cover () includes a support () with a rotatable cap (), where the rotation of the cap causes the shutter () to open. In another embodiment, the cover includes a base and a slidable cap, where the slidable cap is the shutter. The shutter () may be manually actuated, mechanically actuated or electrically actuated. The cover () may be biased to the open position or to the closed position.

A non-interchangeable two-component connecting valve capable of connecting a fuel supply to a fuel cell or other device is disclosed. One component of the connecting valve comprises at least one center post and one internal elastomeric seal, which opens when moved or compressed by a correctly sized and dimensioned mating tube from the other component. In one embodiment, only one valve component has one or more internal seals. In alternate embodiments, both valve components have one or more internal seals, which can open simultaneously or sequentially.

Valves for connecting fuel supplies to a device are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any device, such as fuel cells or fuel refilling apparatus. The valve includes face seals to minimize the amount of fuel remaining in the valve when the fuel supply is separated from the device. In one embodiment, the valve includes deformable members including sealing surfaces, where the flow paths through the valve are sealed and unsealed by the deformation of the deformable members. In another embodiment, the female valve component includes a shortened body to limit the volume of fuel remaining in the valve. The female valve component also includes a cap with slots formed therein so that residual fuel can drain from the valve component into a fuel reservoir.

Disclosed herein are connecting valves with an interchangeability feature () to ensure that the fuel cell fuel matches the fuel cell. Also disclosed are retainer mechanisms () capable of releasably connecting the fuel supply to the fuel cell or to the electronic device equipped with a fuel cell. An improvement to the connecting valves to decrease the amount of residual fuel left in the fuel supply is also provided.

Disclosed herein are multiple embodiments of a hydrogen generator () that measures, transports or stores a single dose of a viscous fuel component from first fuel chamber () in storage area () when the internal hydrogen pressure () of the hydrogen generator is high, and transports this single dose to a metal hydride fuel component in second fuel chamber () 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.
