Patent ID: 8381766

Claim:
A hydrogen generation system comprising: a first supply reservoir and a second supply reservoir respectively for first and second liquid fuel components of a fuel mixture capable of generating hydrogen via a chemical reaction; a reaction zone; a single reversible fuel delivery pump for delivering the fuel components from the first and second reservoir to the reaction zone; first and second conduit lines extending respectively between the first supply reservoir and the reaction zone and between the second supply reservoir and the reaction zone, the reversible pump being disposed between the first and second conduit lines in fluid communication therewith; flow control means comprising a plurality of valves in at least one conduit upstream of the reaction zone; wherein the reversible pump is co-operable with the a plurality of valves, the pump being operable in a first direction to pump the first fuel component from the first reservoir to the reaction zone, and operable in the reverse direction to pump the second fuel component from the second reservoir to the reaction zone; and control means for selecting a duty cycle of the reversible pump for delivering to the reaction zone first and second fuel components in desired proportions.
