    Abstract: An electrolytic cell employs a plastic molded frame component with raised ridges on one surface to create seal with a proton exchange membrane and on the opposite surface a groove with an interlocking feature for accepting a tabbed elastomer gasket. The gasket and frame design when combined with a proton exchange membrane can be stacked in multiple layers using mechanical hardware. The frame captures the softer elastomeric sealing material preventing elastomeric creep and loss of positive seal caused by the relaxation of mechanical hardware under load and internal pressure fluctuations. The addition of the ridged sealing surface provides positive surface contact with the polymeric membrane to further prevent the loss of seal under mechanical load. The interlocking feature reduces assembly time and improves assembly accuracy.

  • Patent number: 7488409
    Abstract: Animal waste is contacted with an electrolyte containing the oxidized form of one or more reversible redox couples, produced electrochemically by anodic oxidation at the anode of an electrochemical cell. The oxidized forms of any other redox couples present are produced either by similar anodic oxidation or reaction with the oxidized form of other redox couples present and capable of affecting the required redox reaction. The oxidized species of the redox couples oxidize the organic waste molecules and are themselves converted to their reduced form, whereupon they are reoxidized by either of the aforementioned mechanisms. The redox cycle continues until all oxidizable waste species, including intermediate reaction products, have undergone the desired degree of oxidation. The entire process takes place between zero degrees centigrade and slightly below the boiling point of the electrolyte, avoiding formation of either dioxins or furans.

    Abstract: Mediated electrochemical oxidation to treats, oxidizes and destroys biological waste, medical, infectious, pathological, animal, sanitary, mortuary, ship, veterinary, pharmaceutical and combined waste. Electrolytes contain oxidized forms of reversible redox couples produced. Oxidized forms of redox couples are produced by anodic oxidation or reaction with oxidized forms of other redox couples. Oxidized species of the redox couples oxidize the biological waste molecules and are reduced and reoxidized. The redox cycle continues until all oxidizable waste and intermediate reaction products have undergone oxidation. Temperatures between ambient and 100° C. avoid formation of dioxins or furans.

  • Patent number: 6875335
    Abstract: An anode as a workpiece, and a cathode opposed to the anode with a predetermined spacing are placed in ultrapure water. A catalytic material promoting dissociation of the ultrapure water and having water permeability is disposed between the workpiece and the cathode. A flow of the ultrapure water is formed inside the catalytic material, with a voltage being applied between the workpiece and the cathode, to decompose water molecules in the ultrapure water into hydrogen ions and hydroxide ions, and supply the resulting hydroxide ions to a surface of the workpiece, thereby performing removal processing of or oxide film formation on the workpiece through a chemical dissolution reaction or an oxidation reaction mediated by the hydroxide ions. Thus, clean processing can be performed by use of hydroxide ions in ultrapure water, with no impurities left behind on the processed surface of the workpiece.

    Abstract: This invention is directed to an integrated onboard hydrogen (H2) production and utilization system for all watercraft, which yields environmentally benign vessel power production without new infrastructure requirements. Water (H2O) is supplied to a vessel, whether ashore, docked or underway, and is systematically converted into hydrogen and oxygen. The energy required for this process may be provided by any renewable or non-renewable source. The H2 produced is either utilized at once or stored. Energy is released from the H2 by one or more power plants.
