US Patent 8940151 Water electrolysis systems and methods

Membrane-less electrolysis systems including an electrolysis chamber having an inlet for water, a cathode associated with the electrolysis chamber that includes a plurality of apertures within the cathode that fluidly couple the chamber with a cathode fluid pathway that is fluidly coupled to a hydrogen gas collector, an anode associated with the electrolysis chamber that similarly includes a plurality of apertures fluidly coupling the chamber with an anode fluid pathway that is fluidly coupled to an oxygen gas collector, a power source electrically coupled to the cathode and anode, and a pump fluidly coupled with the water reservoir and electrolysis chamber so that the pump is configured to pump water into the electrolysis chamber, through the cathode and anode apertures, into the cathode and anode fluid pathways, respectively, and into the product gas collectors.
