    摘要: Edge designs, especially for ePTFE-reinforced membranes for proton exchange membrane (PEM) fuel cells, wherein the designs provide a proton barrier at the electrode edge of the PEM fuel cell membrane electrode assembly (MEA) to provide, among other things, resistance to membrane chemical degradation. A portion of the ePTFE layer is imbibed with a proton-impermeable polymer at the electrode edge. The polymer can include, without limitation, B-staged epoxides, B-staged phenolics, hot melt thermoplastics, and/or thermosets or thermoplastics cast from liquid dispersions.

    摘要: A vaporizer is provided for vaporizing liquid in a fluid stream. The vaporizer includes at least two heat exchangers serially arranged in a direction of flow of the fluid stream through the vaporizer for vaporizing liquid in the fluid stream in stages. The heat exchangers each comprise a first plurality of thermally conductive flow channels through which the fluid stream flows and a second plurality of thermally conductive flow channels through which a heating stream flows and which are in heat exchange relationship with the first plurality of thermally conductive flow channels. A liquid supply means is provided for adding liquid to a downstream heat exchanger. The added liquid mixes with the vaporized stream exiting an upstream heat exchanger for vaporization in the downstream heat exchanger.

    摘要: A method for controlling the power and temperature and fuel source of a combustor in a fuel cell apparatus to supply heat to a fuel processor where the combustor has dual fuel inlet streams including a first fuel stream, and a second fuel stream of anode effluent from the fuel cell and reformate from the fuel processor. In all operating modes, an enthalpy balance is determined by regulating the amount of the first and/or second fuel streams and the quantity of the first air flow stream to support fuel processor power requirements.

    摘要: A burner for heating an exhaust gas stream is disclosed having a combustor head with a fuel/air charge preparation apparatus comprising a fuel nozzle and dual vortex atomizer. The charge preparation apparatus is mounted on one side of a base member or partitioning member having an outlet through which the atomized fuel and air pass to a combustor chamber defined by a combustor tube fixed to a second side of the partition. The combustor tube has an ignitor and outlets for the burning fuel/air mixture. The outlets have flow directing louvers which function to direct the output in a predetermined direction to optimize mixing of the burner output with an exhaust gas stream. The combustor head is mounted through an opening in a housing which positions the combustor tube outlets in the exhaust stream.
