  • Dynamic buoyancy control
    Patent number: 11447218
    Abstract: Underwater apparatuses and methods of operating underwater apparatuses. The apparatus includes a power source such as an aluminum-water cell. Waste product from the power source may be channeled into various portions of the apparatus to adjust the buoyancy of the apparatus, the center of buoyancy of the apparatus, and/or the trim of the apparatus.
    Type: Grant
    Filed: October 4, 2017
    Date of Patent: September 20, 2022
    Assignee: L3Harris Open Water Power, Inc.
    Inventors: David Harvie Porter, Thomas Bradford Milnes, Ian Salmon McKay, Jeffrey Michael Smith
  • Galvanic metal-water cell with nickel-molybdenum cathode
    Patent number: 11069883
    Abstract: Galvanic metal-water cells and methods of manufacturing positive electrodes to be used in said galvanic metal-water cells. The galvanic metal-water cells in accordance with various embodiments include a cathode that includes a layer comprising nickel-molybdenum deposited thereon. The nickel-molybdenum coated cathodes exhibit favorable hydrogen evolution reaction overpotential compared with existing devices. In these galvanic metal-water cells, the metal is oxidized and water is reduced.

  • Pumpless electrochemical cell
    Patent number: 11063276
    Abstract: An electrochemical cell and a method of operating the same. In accordance with various embodiments, the cell includes an anode, one or more cathodes opposite the anode defining a pathway there between. Chemical reactions allow the electrolyte to flow through the defined pathway without requiring a pumping device.

  • Heating using electrochemical power source
    Publication number: 20190365563
    Abstract: A thermal management system and a method of heating a water-surface load or sub-water load. The system includes an electrochemical power source which generates electrical power and heat as a byproduct or coproduct. The electrolyte contained in the electrochemical power source is configured to transport the heat that is generated by the electrochemical power source to at least one water-surface load or sub-water load.
