  • Publication number: 20210016392
    Abstract: A waste product removal system for an additive manufacturing system can include a suction nozzle configured to connect to a suction source for providing suction to a build area of the additive manufacturing system. The waste product removal system can include a shield in operable communication with the nozzle and configured to extend downward near the nozzle to prevent reintroduction of the material ejection to a powder in the build area. The shield can be configured to guide material ejection from the build area to the suction nozzle.

  • Publication number: 20200102844
    Abstract: An assembly for use in an attritable engine includes a hub and a blade. The hub is configured to rotate about a centerline axis passing through a center of the hub and is formed with a first type of layer-by-layer additive manufacturing process. The blade is connected to and extends radially outward from the hub. The blade is formed with a second type of layer-by-layer additive manufacturing process that is different than the first layer-by-layer additive manufacturing process. The hub and the blade are integrally formed together as a single piece of material with a layer-by-layer additive manufacturing process. The blade includes a root of a first material, a platform connected to the root, an airfoil connected to and extending from the platform, and a tip connected on a distal end of the airfoil opposite from the root. The platform includes a material that is different from the first.

  • Patent number: 9455456
    Abstract: An anode exhaust recycle turbocharger (100) has a turbocharger turbine (102) secured in fluid communication with a compressed oxidant stream within an oxidant inlet line (218) downstream from a compressed oxidant supply (104), and the anode exhaust recycle turbocharger (100) also includes a turbocharger compressor (106) mechanically linked to the turbocharger turbine (102) and secured in fluid communication with a flow of anode exhaust passing through an anode exhaust recycle loop (238) of the solid oxide fuel cell power plant (200). All or a portion of compressed oxidant within an oxidant inlet line (218) drives the turbocharger turbine (102) to thereby compress the anode exhaust stream in the recycle loop (238). A high-temperature, automotive-type turbocharger (100) replaces a recycle loop blower-compressor (52).

  • Patent number: 9455455
    Abstract: Fuel cells (38) have passageways (83, 84) that provide water through one or both reactant gas flow field plates (75, 81) of each fuel cell, whereby the fuel cell is cooled evaporatively. The water passageways may be vented by a porous plug (not shown), or by a microvacuum pump (89). A condenser (59) may have a reservoir (64); the condenser (59) may be a vehicle radiator. A highly water permeable wicking layer (90) is disposed adjacent to one or both water passageways (83, 84) which exist between individual fuel cells (38). The passageways may be flow-through passageways (83) (FIG. 5) or they may be interdigitated passageways (83a, 83b) (FIG. 6) in order to increase the flow of water-purging air through the wicking layer (90) utilized to clear the stack of water during shutdown in cold environments.

  • Publication number: 20120315558
    Abstract: The invention is a hydrogen passivation shut down system for a fuel cell power plant (10, 200). During shut down of the plant (10, 200), hydrogen fuel is permitted to transfer between an anode flow path (24, 24?) and a cathode flow path (38, 38?) while a low-pressure hydrogen generator (202) selectively generates an adequate amount of hydrogen and directs flow of the low-pressure hydrogen into the fuel cell (12?) downstream from a hydrogen inlet valve (52?) to maintain the fuel cell (12?) in a passive state.

  • Patent number: 8277991
    Abstract: The invention is a hydrogen passivation shut down system for a fuel cell power plant (10, 200). During shut down of the plant (10, 200), hydrogen fuel is permitted to transfer between an anode flow path (24, 24?) and a cathode flow path (38, 38?). A passive hydrogen bleed line (202) permits passage of a smallest amount of hydrogen into the fuel cell (12?) necessary to maintain the fuel cell (12?) in a passive state. A diffusion media (204) may be secured in fluid communication with the bleed line (202) to maintain a constant, slow rate of diffusion of the hydrogen into the fuel cell (12?) despite varying pressure differentials between the shutdown fuel cell (12?) and ambient atmosphere adjacent the cell (12?).

  • Publication number: 20110318666
    Abstract: A fuel cell is disclosed that includes an electrode assembly arranged between a cathode and an anode. The anode and cathode have lateral surfaces adjoining lateral surface of the electrode assembly and respectively include fuel and oxidant flow fields. Interfacial seals are not arranged between the lateral surfaces. Instead, a sealant is applied to the anode, the cathode and the electrode assembly to fluidly separate the fuel and oxidant flow fields. In one example, the adjoining lateral surfaces are in abutting engagement with one another. The sealant is applied in a liquid, uncured state to perimeter surfaces of the electrode assembly, the anode and the cathode that surround the lateral surfaces.

  • Patent number: 7976992
    Abstract: A PEM fuel cell (4) power plant includes a passive air vent (24) through which air separated from a cathode effluent stream can be expelled from the power plant. The air vent operates satisfactorily during ambient freezing conditions thus it is eminently suitable for use in mobile applications such as in PEM fuel cell-powered automobiles, buses, or the like. The vent is formed from a liquid antifreeze layer (40) that is disposed in a sparging tank (36) which communicates with ambient surroundings. Any water vapor in the stream can condense out of the gas-stream in the antifreeze. In order to facilitate this result, the antifreeze can be a liquid that is immiscible with water so that the condensed water will form a separate layer (38) in the sparging tank.

  • Publication number: 20110136035
    Abstract: A fuel cell is disclosed that includes a cathode, an anode and an electrode assembly, each including lateral surfaces that adjoin one another. The electrode assembly is arranged between the cathode and anode. Each of the cathode, the anode and the electrode assembly include perimeter surfaces transverse to the lateral surfaces that are arranged adjacent to one another. A UV curable sealant is arranged on the perimeter surfaces providing a seal over the lateral surfaces. After the UV curable sealant has been applied to the perimeter surfaces, the sealant is exposed to a UV light source for a desired duration to cure the sealant. Accordingly, the UV curable sealant reduces the complexity of the cell stack assembly and decreases its production time.

  • Publication number: 20110111325
    Abstract: An exemplary fuel cell device includes porous plates. Electrode assemblies (24) are adjacent the porous plates (22). Partially porous plates (26) are adjacent the electrode assemblies (24) on an opposite side from the porous plates (22). The porous plates have coolant channels (32) that are configured to carry a liquid coolant. The partially porous plates have flow field channels (40) on one side that are configured to permit a fluid in the flow field channels to contact the corresponding immediately adjacent electrode assembly (24). An opposite side of the partially porous plates have a non-porous surface (42) that is configured to isolate the partially porous plate from any liquid in the coolant channels (32) of an adjacent one of the porous plates (22). Any liquid in the partially porous plate is exclusively from a reaction at the corresponding immediately adjacent electrode assembly.
