Abstract: The invention relates to a single cell assembly for a fuel cell stack having a framed membrane electrode assembly which comprises an electrochemically active region having two gas diffusion layers and a catalyst-coated membrane which are glued to a frame, with a bipolar plate which has flow-distributing and flow-guiding elements in a flow region corresponding to the electrochemically active region, wherein in an edge region of the bipolar plate surrounding the flow region, on at least one of its surfaces, a sealing groove for receiving a seal between the frame and the bipolar plate extends around the flow region. The single cell assembly according to the invention is characterized in that on at least one surface of the bipolar plate, between the sealing groove and the flow region, a receiving groove for a connection region between the frame and the membrane electrode assembly is arranged.

Abstract: A capo device for stringed instruments, comprising: a substantially J-shaped main body having an elongate arm and a short arm, a pivot arm pivotally coupled with said short arm of said J-shaped main body, an elastomeric component pivotally and compressably coupled between a portion of said elongate arm of said J-shaped main body and a proximal end of said pivot arm and a main arm pivotally coupled with said pivot arm and said main body.

Abstract: Flow field plates in solid polymer electrolyte fuel cells can be subject to ice blockages in certain areas during freeze start-up, e.g. the backfeed ports and slots used in some flow field plate designs which connect an outlet plenum channel for a reactant to its outlet. By incorporating a similar and adjacent relief backfeed port, slot and plenum channel arrangement in which the relief plenum channel is separated from the outlet plenum channel by a landing, a relief outlet for the reactant is provided through the adjacent gas diffusion layer.

Abstract: A bipolar plate assembly with integrated seal for a fuel cell with a subassembly having a formed metal cathode plate bonded to a formed metal anode plate. On at least one of the plates, two raised continuous ridges are formed on the outward surface of and around the perimeter of the plate, thereby creating a channel to contain the seal. In this design, a substantial portion of the channel area on the inward surface of the plate is in direct contact with and supported by the other plate. The channel and hence the seal are thus well supported during molding and under compression in the assembled fuel cell. Further, ducts traversing the seal region can advantageously be formed without affecting the functioning of the seal.

Abstract: The present invention relates to inhibitors of VAP-1 and their use as medicaments in treating fibrotic conditions. Furthermore, the present invention relates to a method of diagnosing a fibrotic condition on the basis of elevated level of soluble VAP-1 or SSAO activity in a bodily fluid, and to a kit for use in said diagnostic method.

Abstract: A wire system comprising a splitter integrated between two wire portions. The wire system can be used to transmit a signal between a signal source and a first output device connected to the wire portions. At any time, a user can choose to couple one or more additional output devices to the splitter to access the same signal being transmitted to the first output device.

Abstract: A composite part made from a sheet molding compound is disclosed as having improved characteristics over traditional sheet molding compound composite parts. The fibrous material is introduced as a veil layer adjacent a paste layer, the veil flows well during the molding process. The improved flow and surface characteristics of a composite part are attributed to the elongation of the veil during molding and to the improved filling capabilities.

Abstract: A hand and digit exercise device having a core section of elastic material surrounding and defining an open space, a plurality of elastic finger loops separate from and disposed about said core section and sized to receive digits of a hand and an elastic connection arm extending between each of said finger loops and said core section whereby said finger loops are attached to said core section at various location around the open space in the core section.

Abstract: Improved water distribution can be obtained within the cells of a fuel cell series stack by maintaining a suitable temperature difference between the cathode and anode sides of each cell in the stack during shutdown. This can be accomplished by thermally insulating the “hot” end and sides of the stack and by providing a thermal mass adjacent to the “hot” end.

Abstract: A finger exercise device is comprised of an elastic elongated central loop and elastic side loops attached to opposite ends of the central loop. The loops are for being worn around a plurality of fingers, and the exercise is comprised of repeatedly spreading the fingers apart against the tension of the loops. The central loop has a varying width between its opposite edges, wherein the opposite ends of the loop are wider than the intermediate portion for improved grip and comfort on the fingers. The side loops have outer ends which are wider than the inner ends for improved grip and comfort. In an alternative embodiment, the finger exercise device is comprised of a plurality of loops, and radial arms extending from a solid junction are connected to respective loops. The loops have widened outer ends for improved grip and comfort.
