  • Publication number: 20120202127
    Abstract: An electrochemical cell system is configured to utilize an ionically conductive medium flowing through a plurality of electrochemical cells. One or more disperser chambers are provided to disrupt or minimize electrical current flowing between the electrochemical cells, such as between the cathode of one cell and the anode of a subsequent cell by dispersing the ionically conductive medium. Air is introduced into the disperser chamber to prevent the formation of foamed ionically conductive medium, which may reconnect the dispersed ionically conductive medium, allowing the current to again flow therethrough.

  • Publication number: 20120121992
    Abstract: A rechargeable cell includes an air electrode for absorbing and reducing oxygen to a reduced oxygen species during discharge and oxidizing the reduced oxygen species during recharge to evolve oxygen. An outer surface of the air electrode is permeable to oxygen and water. A fuel electrode of the cell includes a metal fuel that it oxidizes during discharge and reduces during recharge. First and second ionically conductive layers of the cell have an interface therebetween. The first layer is between an inner surface of the air electrode and the interface. The second layer is an ionic liquid between an inner surface of the fuel electrode and the interface. The first layer is hygroscopic and the ionic liquid is hydrophobic so water absorbed through the air electrode is essentially prevented from diffusing across the interface into the ionic liquid.

  • Patent number: 8168337
    Abstract: The present invention relates to an electrochemical cell for use with an electrolyte, oxidizable solid fuel, and an oxidizer to generate electrical power. The electrochemical cell includes a permeable electrode body provided along a flow path for receiving a flow including an electrolyte. The permeable electrode body is configured to permit the electrolyte to flow therethrough and to collect solid fuel thereon from the electrolyte flowing therethrough so as to comprise a first electrode for oxidizing the fuel to generate electrons for conduction by the first electrode. The cell also includes a second electrode for receiving electrons and reducing an oxidizer. The first electrode and the second electrode are spaced apart to define a gap therebetween for receiving the flow from the permeable electrode body. One or more return channels are directly communicated to the gap.

  • Publication number: 20120098499
    Abstract: An electrochemical cell includes a fuel electrode configured to operate as an anode to oxidize a fuel when connected to a load. The cell also includes an oxidant electrode configured to operate as a cathode to reduce oxygen when connected to the load. The fuel electrode comprises a plurality of scaffolded electrode bodies. The present invention relates to an electrochemical cell system and method of resetting the electrochemical cell by applying a charge (i.e. voltage or current) to the cell to drive oxidation of the fuel, wherein the fuel electrode operates as an anode, and the second cell operates as a cathode, removing uneven distributions of fuel that may cause premature shorting of the electrode bodies to improve capacity, energy stored, and cell efficiency.
