  • Patent number: 10553879
    Abstract: A method of making an interconnect for a solid oxide fuel cell stack includes providing a chromium alloy interconnect and providing a nickel mesh in contact with a fuel side of the interconnect. Formation of a chromium oxide layer is reduced or avoided in locations between the nickel mesh and the fuel side of the interconnect. A Cr—Ni alloy or a Cr—Fe—Ni alloy is located at least in the fuel side of the interconnect under the nickel mesh.

  • Publication number: 20160301082
    Abstract: A method for forming a solid oxide fuel cell (SOFC) includes co-firing the anode and cathode electrode layers, which involves placing an unfired anode onto a surface during the cathode print cycle. To avoid damage to the electrolyte and cathode production cycle by the green anode ink, an abrasion resistant ink is used to print the anode electrode layer.

  • Patent number: 7497823
    Abstract: A stabilizing device having a flexible shaft with a terminal connector and surgical tools used therewith. The flexible shaft is responsive to a tension element connected to a distal end of the shaft and in communication with a proximal end of the shaft. An elastic means interfacing between the proximal end of the tension element and an actuating cam cause the shaft to adapt for differences in activating tension between straight and curved positions. Accordingly, stretching and deformation of the tensioning element is reduced and shaft stiffness upon activation of the tensioning element is repeatable. The terminal connector includes a ball-and-socket arrangement adapted to resiliently absorb movement of an organ during surgery. A bendable suction stabilizer foot adaptable to contours of an organ is also provided as an attachment to the stabilizer device.

  • Publication number: 20050113821
    Abstract: Stapler and ablation clamping heads can be interchangeably coupled to a hand-operated actuation mechanism using a quick connect/quick release coupling. In the actuation mechanism, a first user-operable lever controls clamping of the jaws of either head, while a second user-operable lever controls the firing of staples in the stapler head. A removable staple holder may be used with the stapler head to allow easy reloading of staples as well as the use of different sizes and type of staples. A corresponding removable anvil may be used as well. A removable electrode holder may be used with the ablation head to allow the use of different electrode configurations. Moreover, a removable electrode holder may be used over the jaws of a stapler head as an overlay.
