  • Patent number: 8834687
    Abstract: A layered construction for use in decontaminating a surface or enclosed space is described. The construction is an electrochemical cell which includes a cathode, an electrolyte layer, an anode and a protective surface layer. A precursor compound that can be electrically decomposed to release an oxidant, on demand and over an extended period of time, is included in the layered structure, preferably in the electrolyte layer. The oxidant compounds react with various different chemical or biological contaminants in contact the protective layer, thereby deactivating, destroying or devitalizing the contaminants. The layered construction is suitable for application to a device or substrate, or placement in an enclosed space, and can be used on sensitive surfaces such as electronic components and human skin.

  • Patent number: 8784619
    Abstract: A portable, on-demand hydrogen generation system is provided for producing hydrogen and injecting the hydrogen as a fuel supplement into the air intake of internal combustion engines, more particularly to vehicles. Hydrogen and oxygen is produced with a fuel cell at low temperatures and pressure from water in a supply tank. The hydrogen and oxygen is passed back thru the supply tank for distribution and water preservation. The gases are kept separate by a divider in the tank and the water level in the tank. In the case of gasoline engines, the hydrogen is directed to the air intake of the engine while the oxygen is vented to the atmosphere. The device is optionally powered by the vehicle battery, a stand alone battery, waste heat of the internal combustion engine or solar energy. The system utilizes a vacuum switch or other engine sensor that permits power to the device and therefore hydrogen production only when the engine is in operation.

    Abstract: Ketones, specifically Methyl ethyl ketone (“MEK”) and octanedione, may be formed from six carbon sugars. This process involves obtaining a quantity of a six carbon sugar and then reacting the sugar to form levulinic acid and formic acid.

The alkali metal levulinate is placed in an anolyte along with hydrogen gas that is used in an electrolytic cell. The alkali metal levulinate within the anolyte is decarboxylated to form MEK radicals, wherein the MEK radicals react with hydrogen gas to form MEK, or MEK radicals react with each other to form octanedione. The alkali metal formate may also be decarboxylated in the cell, thereby forming hydrogen radicals that react with the MEK radicals to form MEK.

  • Patent number: 8709220
    Abstract: Each unit cell of a water electrolysis apparatus includes a pair of an anode separator and a cathode separator and a membrane electrode assembly interposed between the pair of separators. The anode separator has a first flow field to which water is supplied, and the cathode separator has a second flow field for producing high-pressure hydrogen through electrolysis of the water. A second seal groove for receiving a second seal member is disposed annularly around the second flow field. A pressure-releasing chamber is disposed outwardly of the second seal groove, is capable of communicating with the second seal groove and communicates with the outside through a depressurizing channel.

  • Patent number: 8702915
    Abstract: Small, autonomous, low cost electrochemical gas generators containing an electrochemical cell assembly, a commercially available battery and a current controlling mechanism. Current control, which defines the gas generation rate, is achieved either electronically by means of a resistor or through mass transfer control by means of a gas permeable film of known permeability. In either case, the gas generation rates are generally from 0.1 to 10 cc/day. The gas source must contain an electrochemically active gas such as oxygen or hydrogen. Air is the preferred source for oxygen. These miniature gas generators, generally are less than 1.5 cm in diameter and length, require novel, compact, electrochemical cell assemblies. Various cell assemblies, generally 1 cm in diameter and less than 0.5 mm thick, are described. These miniature gas generators are used for the controlled release of fluids such as pheromones, fragrances, insect repellents, and the like.

  • Publication number: 20140097083
    Abstract: A transient distribution of electron quasiparticles with elevated effective mass is created by adding a targeted range of both crystal momentum and electron energy in a conductor to place electrons into regions of the electronic band structure diagram having a chosen, desired curvature. Effective mass scales as the inverse of curvature. The quasiparticles form transient bonds with delocalized ions and other reactants in or on a reaction particle where reaction rates and branches are controlled by the choice of effective mass.

  • Publication number: 20140051007
    Abstract: The present disclosure is directed towards the design of electrochemical cells for use in high pressure or high differential pressure operations. The electrochemical cells of the present disclosure have non-circular external pressure boundaries, i.e., the cells have non-circular profiles. In such cells, the internal fluid pressure during operation is balanced by the axial tensile forces developed in the bipolar plates, which prevent the external pressure boundaries of the cells from flexing or deforming. That is, the bipolar plates are configured to function as tension members during operation of the cells. To function as an effective tension member, the thickness of a particular bipolar plate is determined based on the yield strength of the material selected for fabricating the bipolar plate, the internal fluid pressure in the flow structure adjacent to the bipolar plate, and the thickness of the adjacent flow structure.
