Latest Patents

Huddleston's latest patents include a fuel unit, a refillable hydrogen generator, and a fuel cell system. The packaged fuel unit and refillable hydrogen generator are designed to produce hydrogen gas through a thermal decomposition reaction. This process occurs when the reactant within the package is heated to a specific temperature. The design incorporates a poor thermal conductor with sections that effectively transfer heat to the reactant. Additionally, the hydrogen generator features a holder that allows for the removable placement of the fuel unit, along with a heating system that activates when the fuel unit is in position.

Another significant patent involves a heater assembly for the hydrogen generator. This assembly can be retracted to allow for easy insertion and removal of the replaceable fuel unit without causing damage. When the heater is energized, it extends to make contact with the fuel unit, ensuring efficient operation. Conversely, when de-energized, the assembly retracts, creating a gap to protect the components.
