  • Publication number: 20130149631
    Abstract: A device for a solid oxide fuel cell or a solid oxide electrolysis cell includes an integral one-piece construction of a current collector and a manifold. The device eliminates the need for a brazing or thermal bonding process for joining the manifold with the current collector, and thus makes it possible to prevent breakdown of the junction formed between the manifold and the current collector, which can lead to gas leakage through the junction, and thus can be used for a long period of time.

  • Publication number: 20120024698
    Abstract: The invention provides a self supporting isobaric structure for electrolyte aeration in an electrodeposition cell for electrolytic refining or winning of non-ferrous metals, and a method of fabrication thereof. The structure is constructed using thermoplastic material pipes the external surface of which is wrapped in a thermosetting polymer composite material and one or more successive wrapped layers of fiber glass mats, thus forming a structural monoblock. The pipes are arranged in a reticular layout having a generally rectangular frame that follows the contour of the cell, transverse structural elements that connect the longer sides of the frame and tubular elements connecting the shorter sides of the rectangular frame. The tubular element provide a means for gas diffusion and aeration in the cell. Furthermore, the invention provides pipe couplings that allow shorter elements to be connected together in order to achieve the reticular configuration.

  • Patent number: 8083910
    Abstract: An insulating spacer 30 comprises a plurality of unit spacers 40, and a flexible coupling portion 41 for coupling the unit spacers 40 along the axial direction thereof, wherein the unit spacer 40 comprises a plurality of annular plates 42 and 43 each having an insertion hole 44 for inserting the auxiliary anode 11, and a coupling frame 45 for coupling the annular plates 42 and 43 in the axial direction of the auxiliary anode 11 while opening the outer circumference side thereof. The auxiliary anode unit 10 is constituted by inserting the insulating spacer 30 into the auxiliary anode 11, and since each unit spacer 40 is coupled, the distal end of the auxiliary anode 11 is naturally located in proximity to the insertion hole 44 provided in the next unit spacer 40 when the auxiliary anode 11 penetrates one unit spacer 40. Accordingly, the auxiliary anode 11 can be inserted into the insulating spacer 30 by series of works, and as a result, the auxiliary anode unit 10 can be manufactured with good workability.

  • Patent number: 8029296
    Abstract: A nonmetallic electrical contact or wiper composed of a composite carbon fiber material through which an electrical signal is terminated. The carbon fibers are arranged in and bonded into a multi-layer structure used to conduct a primary electrical signal. A nonwoven carbon fiber mat is used as one or more of the layers structure, which also includes one or layers of carbon fiber, aligned substantially in the same direction, and encapsulated within a matrix of electrometric material. This mat also improves an off-axis conductivity of the material and provides increased mechanical stability required for the fabrication of electrical contacts or wipers produced using this material.
