  • Patent number: 8951691
    Abstract: A solid oxide fuel cell stack is disclosed. In one aspect, the solid oxide fuel cell stack includes unit cells, an external collector, a first stack collecting member, a cap, and a suspension member. The external collector contacts an outer periphery of each of the unit cells and electrically connects the unit cells to each other. The first stack collecting member is positioned to collect current from a distal unit cell. A cap is provided in one end of the distal unit cell. The suspension member has one side thereof suspended from the cap and the other side fixed to the first stack collecting member to distribute weight of the first stack collecting member. Structural stability of a stack collector may be maintained even at oxidizing atmosphere of high temperature when driving the fuel cell stack.

  • Publication number: 20150030954
    Abstract: The present invention relates to a redox flow secondary battery. The redox flow secondary battery of the present invention comprises a unit cell including a pair of electrodes made of a porous metal, wherein the surface of the porous metal is coated with carbon. According to the present invention, a redox flow secondary battery using porous metal electrodes uniformly coated with carbon is provided, thus improving conductivity of the electrodes, and the electrodes have surfaces uniformly coated with a carbon layer having a wide specific surface area, thus improving reactivity. As a result, capacity of the redox flow secondary battery and energy efficiency can be improved and resistance of a cell can be effectively reduced. Further, the electrodes are uniformly coated with a carbon layer, thus also improving corrosion resistance.
