Patent ID: 8273140

Claim:
An apparatus for producing high purity hydrogen from water comprising: a reaction vessel having a first chamber for receiving a plurality of reactant capsules prior to addition of reaction water to the vessel and a second chamber to accommodate the reaction water from the first chamber when a reaction between the reactant capsules and the reaction water is stopped, the first chamber and second chamber being divided by a partition, with a lower end of the partition suspended above and distanced from a bottom of the reaction vessel, thereby permitting fluid communication between the first and second chambers underneath the partition; a piston and tension spring assembly coupled to a top portion of the second chamber to accommodate pressure that builds up from the reaction between the reactant capsules and the reaction water; a supporting grid contained in the first chamber to support the plurality of reactant capsules, the supporting grid located above and distanced from a bottom of the first chamber, and the supporting grid permitting the reaction water therethrough; an inlet for adding the reaction water said inlet disposed at a top portion of the first chamber of the vessel with a cap attached; an outlet for releasing hydrogen, disposed at the top portion of the first chamber, said outlet including a valve to stop a flow of hydrogen and move the reaction water to the second chamber; and an outlet for dislodging a waste solution of the reaction, disposed at the bottom of the first chamber of the reaction vessel.
