Abstract
A hydrogen generating fuel cartridge includes a case having a perforated opening layer. A hydrogen producing fuel is disposed within the case. A hydrogen permeable membrane is disposed between the hydrogen producing fuel and the perforated opening layer in the case. A spring loaded slideable valve plate is positioned adjacent the perforated opening layer such that the slideable valve plate and perforated opening form a valve that is biased in a closed position to prevent hydrogen from escaping from the fuel cartridge.

1-20. (canceled)
A method comprising:
- inserting a fuel cartridge into a power generator opening;
- engaging a valve spring while inserting the fuel cartridge;
- moving a perforated slideable valve in the fuel cartridge from a spring-loaded closed position to an open position when the fuel cartridge is fully inserted into the power generator opening, wherein selected slideable valve perforations are shaped to provide an exponential gas valve control function when the perforated slideable valve is moved.
A fuel cartridge comprising:
- a case having a perforated opening layer;
- a perforated spring loaded slideable valve plate positioned adjacent the perforated opening layer, such that the slideable valve plate and perforated opening form a valve that is biased in a closed position to prevent gas from escaping from the fuel cartridge;
- wherein the slideable valve plate is perforated to overlap perforations in the perforated opening layer when the valve is open to allow gas to pass through the overlapped perforations;
- and
- wherein selected perforations are shaped to provide an exponential valve control function when the slideable valve plate is moved.
