  • Publication number: 20150303491
    Abstract: Provided are a current collector for a fuel cell and a stack structure having the same. The fuel cell includes an electrolyte layer, and an air electrode layer and a fuel electrode layer on both surfaces of the electrolyte layer and generates electricity, and the current collector includes an even surface configured to electrically surface-contact with the air electrode layer or the fuel electrode layer; and a plurality of openings punched so that air or a fuel gas directly contacts with the air electrode layer or the fuel electrode layer.

  • Publication number: 20150263372
    Abstract: Disclosed is a solid oxide fuel cell stack. The solid oxide fuel cell stack includes a unit cell, a cell frame configured to support an edge of the unit cell, a interconnecting member disposed under the cell frame, a sealing member disposed between the cell frame and the interconnecting member, and a spacer member configured to uniformly maintain an interval between the cell frame and the interconnecting member. The spacer member is disposed at an area between the cell frame and the interconnecting member, which is not sealed by the sealing member, and formed of a mica or insulating ceramic.

  • Publication number: 20150222053
    Abstract: A connector assembly includes a first connector and a second connector. The first connector includes a first main body, a guide member disposed on a side surface of the first main body, and a connecting member disposed on the first main body. The second connector is configured to be combined with the first connector. The second connector includes a second main body, a fixing member disposed on a side surface of the second main body and rotatably connected to each side surfaces at an end portion of the second main body, and a connecting pad disposed on the second main body to contact with the connecting member. Thus, the first connector and the second connector may combine and separate easily, so that a damage of the connector assembly may be prevented.

  • Publication number: 20150180075
    Abstract: Provided is a stacked structure for a fuel cell in which the plurality of fuel cells are stacked. Each of the fuel cells includes an electrolyte layer, and a cathode layer and an anode layer disposed on both surfaces of the electrolyte layer. The stacked structure includes at least one interconnector, at least one frame, and at least one complex functional part. The interconnector includes a central area electrically connected to the fuel cell, and edge area outwardly extending with respect to end portions of the fuel cell. The frame supports a side portion of the fuel cell to reinforce strength of the fuel cell supported by the interconnector. The complex functional part is disposed between the interconnector and the frame to constantly maintain an interval therebetween.

  • Publication number: 20140038082
    Abstract: Disclosed is a connector for a solid oxide fuel cell, which electrically connects tubular solid oxide fuel cells to each other. The connector includes a conductive body part having a first electrode contact groove and a second electrode contact groove. A first electrode contact part is formed on the top surface of the body part to receive at least a portion of an exposed first electrode portion and second electrode portion of a first solid oxide fuel cell, and is electrically connected to the first electrode of the first solid oxide fuel cell. A second electrode contact part is formed at the bottom surface of the body part so as to receive at least a portion of exposed first electrode portion and second electrode portion of a second solid oxide fuel cell, and is electrically connected to the second electrode of the second solid oxide fuel cell.
