  • Patent number: 8663870
    Abstract: An electrochemical device capable of improving arrangement efficiency of bonded bodies and securing favorable sealing characteristics is provided. An electrolyte membrane 11 has a reaction region 11A sandwiched between a fuel electrode 12 and an oxygen electrode 13 and a peripheral region 11B exposed from between the fuel electrode 12 and the oxygen electrode 13. A connection member 20 has a bent section 23 between two flat sections 21 and 22. Since an adhesive layer 14 is provided in the peripheral section 11B of the electrolyte membrane 11, and the bent section 23 of the connection member 20 is bonded to the adhesive layer 14, arrangement efficiency of a bonded body 10 is improved, and favorable sealing characteristics are secured. The adhesive layer 14 has a structure in which a first contact layer having high adhesion to the electrolyte membrane 11, a barrier layer, a strength retention layer, and a second contact layer having high adhesion to the connection member 20 are sequentially laminated.

  • Patent number: 8658327
    Abstract: Various aspects of solid oxide fuel cell (SOFC) technology are described. One specific application includes a seal for connecting an outer surface of a fuel cell to a cell manifold that supports the fuel cell and delivers a fuel mixture to an inside portion of the fuel cell. The seal also separates the fuel mixture from the outer surface at the seal. And the seal is electrically conductive to allow flow of electric current between the outer surface and the cell manifold.

  • Patent number: 8658330
    Abstract: A composite seal having a multilayer elastomeric construction and method for constructing the same is provided. More specifically, the present invention provides a composite seal comprised of a low-durometer elastomer compliant layer coated with, or alternatively encapsulated by, a thin protective layer for securely sealing a bipolar plate and a membrane electrode assembly of a fuel cell. The elastomer compliant layer is preferably a silicone constituent and the thin coat protective layer is preferably a fluoroelastomer or fluoropolymer constituent suitable for bonding to the elastomer compliant layer. The foregoing layers constructing the composite seal are preferably deposited directly onto the aforementioned fuel cell components along a predetermined periphery. The resulting composite seal is thin in construction, resistive to undesired chemical and thermal reactions and provides the necessary compressive compliance without undue stress on the fuel cell assembly.

    Abstract: A system and method for electrically interconnecting a plurality of fuel cells to provide dense packing of the fuel cells. Each one of a plurality of fuel cells has a plurality of discrete electrical connection points along an outer surface. Electrical connections are made directly between the discrete electrical connection points of adjacent fuel cells so that the fuel cells can be packed more densely. Fuel cells have at least one outer electrode and at least one discrete interconnection to an inner electrode, wherein the outer electrode is one of a cathode and an anode and wherein the inner electrode is the other of the cathode and the anode. In tubular solid oxide fuel cells the discrete electrical connection points are spaced along the length of the fuel cell.
