Patent ID: 7105033

Claim:
A hydrogen gas generation system, said system comprising: (a) a housing having a hydrogen separation chamber and a fuel storage chamber and having a partition separating the hydrogen separation chamber from the fuel storage chamber, the fuel storage chamber containing a fuel material capable of reacting to generate hydrogen gas; (b) a catalyst chamber containing a catalyst to promote the reaction of the fuel material to generate hydrogen and discharged fuel material, (c) a fuel conduit for conveying the fuel material from the fuel storage chamber to the catalyst chamber and a outlet conduit to convey the discharged fuel material from the catalyst chamber to the hydrogen separation chamber, (d) a hydrogen gas outlet in the housing for discharging hydrogen from the hydrogen separation chamber, and (e) a gas permeable membrane located in at least one of the fuel storage chamber or the hydrogen separation chamber to allow the hydrogen gas to pass through the gas permeable membrane while preventing an aqueous solution to pass through the gas permeable membrane.
