  • Publication number: 20240172830
    Abstract: A light-emitting system is provided which is removably attachable to headgear for personal illumination to enhance visibility of the user to others. The light-emitting system includes a housing that defines a receiving aperture and is configured to surround a portion of the headgear when the light-emitting system is removably attached to the headgear for use. The light-emitting system further includes at least one lens and a plurality of lighting elements coupled to the annular housing which are configured to selectively generate a halo or at least a partial halo of light that radiates outwardly away from the annular housing through the at least one lens to provide enhanced personal illumination.

  • Publication number: 20140242482
    Abstract: Processes and systems for operating molten carbonate fuel cell systems are described herein. A process for operating a molten carbonate fuel cell system includes providing a hydrogen-containing stream comprising molecular hydrogen to an anode portion of a molten carbonate fuel cell; controlling a flow rate of the hydrogen-containing stream to the anode such that molecular hydrogen utilization in the anode is less than 50%; mixing anode exhaust comprising molecular hydrogen from the molten carbonate fuel cell with a hydrocarbon stream comprising hydrocarbons, contacting at least a portion of the mixture of anode exhaust and the hydrocarbon stream with a catalyst to produce a steam reforming feed; separating at least a portion of molecular hydrogen from the steam reforming feed; and providing at least a portion of the separated molecular hydrogen to the molten carbonate fuel cell anode.

  • Patent number: 8563186
    Abstract: The present invention is directed to systems and processes for operating molten carbonate fuel cell systems. A process for operating the molten carbonate fuel cell includes providing a hydrogen-containing stream comprising molecular hydrogen to a molten carbonate fuel cell anode; heating a hydrocarbon stream, at least a majority of which is comprised of hydrocarbons that are liquid at 20° C. and atmospheric pressure, with a heat source comprising an anode exhaust from the molten carbonate fuel cell anode; contacting at least a portion of the heated hydrocarbon stream with a catalyst to produce a steam reforming feed comprising gaseous hydrocarbons, hydrogen, and at least one carbon oxide; separating at least a portion of the molecular hydrogen from the steam reforming feed; and providing at least a portion of the separated molecular hydrogen to the molten carbonate fuel cell anode as at least a portion of the stream comprising molecular hydrogen.
