US Patent 7459065 Hydrogen generator photovoltaic electrolysis reactor system

An apparatus for creating hydrogen from the disassociation of water using sunlight (photoelectrolysis) is provided. The system utilizes an aqueous fluid filled container which functions both to hold the water to be disassociated and as a light collecting lens. A photovoltaic module is positioned at a point to most efficiently accept the refracted light from the fluid filled container. A pair of electrodes which are coupled to the photovoltaic module are disposed within the fluid and configured to split the water into hydrogen and oxygen.
