Patent ID: 7727373

Claim:
An apparatus for production, recovery and storage of hydrogen gas from an aqueous medium, said apparatus comprising: a photovoltaic cell having a lens, an anode portion and a cathode portion; a conductive canister comprising a top portion having inner walls defining a cell chamber for housing a base of said photovoltaic cell and a bottom portion having a plurality of side openings for allowing passage of said aqueous medium, said conductive canister having an open top end disposed opposite an open bottom end, wherein said inner walls of said cell chamber are in communication with said anode portion of said photovoltaic cell; a removable floatation collar for vertically floating said apparatus with only said lens of said photovoltaic cell above the water line of said aqueous medium; a non-conductive top washer having a central aperture, said non-conductive top washer disposed along the underside of said photovoltaic cell; a removable hydrogen absorption rod comprising a zeolite core material capable of hydrogen absorption disposed on the surface of a conductive rod, said conductive rod having a top end and a bottom end, said top end of said conductive rod being in communication with said cathode portion of said photovoltaic cell as said conductive rod is passed through said central aperture of said non-conductive top washer; and a removable non-conductive bottom end cap attached to said open bottom end of said conductive canister, said removable non-conductive bottom end cap being in communication with said hydrogen absorption rod, wherein said hydrogen absorption rod is capable of being removed from said apparatus when said bottom end cap is removed from said open bottom end of said conductive canister.
