  • Publication number: 20140234740
    Abstract: In one embodiment, a membrane electrode assembly of a fuel cell has an anode aspect and a cathode aspect. A fuel distribution structure is disposed adjacent to the anode aspect. The fuel distribution structure has a fuel feed port configured to receive and inject liquid fuel to a flow field plate. The flow field plate has flow channels formed therein that split and spread from the fuel feed port to exit ports. The flow channels are configured to convey heat to fuel passing there through to substantially convert the liquid fuel to vaporous fuel within the flow channels. The exit ports are configured to deliver the resulting vaporous fuel to the anode aspect to substantially uniformly distribute fuel across the anode aspect. Further, an enthalpy exchanger and heat spreader assembly is in thermal contact with the fuel distribution structure and configured to provide to it heat from fuel cell operation.

  • Patent number: 8735012
    Abstract: A fuel cell system which includes a fuel distribution structure that uniformly distributes vaporizing fuel to a fuel cell is provided. As the fuel travels in a flow field channel in the fuel distribution structure, it is substantially converted to a vapor by the heat of the fuel cell operation in such a manner that the resulting vapor pressure works to substantially uniformly distribute fuel evenly outwardly across substantially the entire active area of the anode aspect of one or more membrane electrode assemblies in the system, and whereby localized, uneven “hot spots” of fuel at the anode aspects are substantially prevented. A pair of enthalpy exchanger and heat spreader assemblies include a cathode current collector element that also has a heat spreader plate that collects and redirects heat in the fuel cell system, the assembly acting to manage the heat, temperature and condensation in the fuel cell system.

  • Publication number: 20120052282
    Abstract: A novel molded fabric is made by bringing a first patterned group of numerous discrete disjoint elements positioned on a first side of a contact boundary extending throughout the thickness of the fabric being molded, together with a second patterned group of numerous discrete disjoint elements, over-lapping the first group of discrete disjoint elements, on the opposite side of the contact boundary, and joining the elements together at their tip portions. Various techniques are disclosed for maintaining separation of overlapping cross-over portions of the thread elements crossing each other during joining the terminal portions together, so that they simulate woven cloth. First and second rolls can carry the elements in molten form within cavities in the roller surfaces or patterns of solid elements within first and second matrices, can be joined together at the nip of the rolls by heat or chemical means to produce substantial savings in fabric manufacture.

  • Publication number: 20100124683
    Abstract: A heat spreader assembly that provides electrical, thermal and structural functions to the fuel cell. The heat spreader assembly comprises two bulk composite material layers, and a heat spreader element. The heat spreader element includes a copper layer sandwiched between two stainless steel layers. The stainless steel layers are bonded to the bulk composite layers by a conductive thermal set adhesive. The lamination applied to the stainless steel layers enables heat and electricity to flow from the cathode while maintaining low resistance among other layers of the fuel cell. The copper layer diffuses heat across the layer and functions as cathode current collector for a fuel cell. The bulk composite material layers function as a cold side of an enthalpy exchanger system and a cathode flow field. Further the composite material includes flow channels formed throughout the material to evenly distribute incoming air over the enthalpy exchanger membrane and to the cathode of the MEA.

  • Publication number: 20100124676
    Abstract: A system and method for managing gas bubbles in a liquid flow system are described. In particular, according to the system and method, novel techniques reduce a volume of cavities in the liquid flow system and limit a cross-sectional area of the liquid flow system to a maximum cross-sectional area of tolerably sized bubbles. In this manner, by reducing the cavity volumes and limiting cross-sectional areas, the formation of intolerably sized bubbles and the aggregation of tolerably sized bubbles into intolerably sized bubbles are each substantially prevented. Also, bubbles may be removed from the system to reduce the quantity of bubbles that are to be managed.

  • Patent number: 7439457
    Abstract: The higher the reading of relative density, liquid weight per unit volume, of pieces of produce such as fruits, the juicier the piece of produce is. By comparing a number of pieces of produce of the same type and species and ranking them, the juiciest pieces of produce may be easily selected and purchased by a shopper. An arrangement of linkages and a sliding spring element creates a device with two inputs, one input being proportional to the volume of the produce based on a representative diameter, and the other input being an approximation of the weight of the produce based on the deflection of a spring. The two inputs are mechanically combined to create one output indicative of density, and thus juiciness, and a pointer is employed whose deflection is proportional to the quotient of the weight and volumetric inputs of each piece of produce tested by the shopper.

  • Patent number: 6038403
    Abstract: A camera housing a strip of receiving sheet of self-developable film material; a strip of negative photosensitive film material of the self-developing type having discrete exposable portions spaced apart thereon. A pressure applying assembly e merges the strips into the superimposable relationship to form corresponding separated image forming subassemblies in response to pulling the strips from the camera. The assembly effects release of processing fluid in rupturable containers on the sheet to initiate processing of the film. A device is operative in one mode for allowing pulling of the strips and thereby the formation of an image forming subassemblies through the pressure applying device, and in a second mode for automatically stopping formation and processing of a successive one of the image forming subassemblies. In one embodiment, the device is connected to the shutter unit and is operated when the shutter is actuated.
