  • Patent number: 8968432
    Abstract: An on-board fuel processor includes a microchannel steam reforming reactor (30) and a water vaporizer (40) heated in series with a combustion gas. The reformer (30) and the vaporizer (40) are both of a cross-flow panel configuration that allows for low combustion side pressure drop. Fuel is directly injected into the steam, and during a rapid cold start, both the combustion gas flow rate and the steam to carbon ratio are substantially increased relative to their steady state operating values. A rapid cold start can be achieved in under 30 seconds with a manageable amount of electric power consumption, removing impediments to use in automotive fuel cell applications.

  • Patent number: 8916302
    Abstract: A method and apparatus for improving the water balance in a power unit by providing the exhaust gas from the cathode side of the fuel cell as a feed gas to the combustion system condensing at least a portion of water present in the effluent from the combustion system in a condenser, and then transferring water vapor from the uncondensed portion of the effluent from the condenser to the gas fed to the cathode side of the fuel cell. Water from the exhaust gas from the cathode side of the fuel cell is either captured in the condenser, or is reused in the feed gas of the cathode side of the fuel cell. By humidifying the air fed into system with the water vapor present in the exhaust gas, water is not lost from the system. Instead, the air is being fed into the system is humidified with this water, which in turn allows the humidifier to operated at higher temperatures and/or use smaller radiators and fans and/or draw less parasitic power, thereby increasing overall system efficiency.

  • Patent number: 8666235
    Abstract: The efficiency and effectiveness of apparatuses for vaporizing and combusting liquid fuel can be improved using thermal conductors. For example, an apparatus having a liquid fuel vaporizer and a combustion chamber can be characterized by a thermal conductor that conducts heat from the combustion chamber to the vaporizer. The thermal conductor can be a movable member positioned at an insertion depth within the combustion chamber that corresponds to a rate of heat conduction from the combustion chamber to the vaporizer. The rate of heat conduction can, therefore, be adjusted by positioning the movable member at a different insertion depth.

  • Patent number: 8394544
    Abstract: The present invention is a Solid Oxide Fuel Cell Reforming Power System that utilizes adiabatic reforming of reformate within this system. By utilizing adiabatic reforming of reformate within the system the system operates at a significantly higher efficiency than other Solid Oxide Reforming Power Systems that exist in the prior art. This is because energy is not lost while materials are cooled and reheated, instead the device operates at a higher temperature. This allows efficiencies higher than 65%.

  • Patent number: 7899309
    Abstract: Apparatus for vaporizing liquid in a vaporization pathway having an actively controlled temperature are disclosed according to some aspects. The apparatus can comprise a first body having a cross sectional shape and dimensions substantially equal to the cross sectional shape and dimensions of a cavity in a second body, which allows the first body to be non-permanently inserted into the second body. The outer surface of the first body, the inner surface forming the cavity in the second body, or both can be modified to create a vaporization pathway between the first and second bodies when the surfaces mate and/or align. The liquid vaporizer can further comprise a vaporization pathway inlet for fluid comprising liquid, a vaporization pathway outlet for fluid comprising primarily vapor, and a heater in thermal communication with the first body, the second body, or both. The heater provides active control of the temperature of the vaporization pathway.

  • Patent number: 7862633
    Abstract: A system and method for creating reformate with decreased carbon deposition. The system is made up of a steam source, a superheater, a fuel injection device, a prereformer, and a reformer with catalyst linings. The system functions to superheat steam while maintaining the fuel at a lower temperature prior to injection and mixing with the steam. After injection and mixing, the steam and fuel mixture is then passed through a prereformer where catalysts treat a portion of the fuel and steam mixture. After these portions are treated with a catalyst, the mixture is passed through to a reformer where further treatment of the material by catalyst takes place.

  • Publication number: 20090113796
    Abstract: A highly compact reforming system made up of arrangements of individual reactor panels interconnected by a joint piece. This arrangement allows for a compact reforming system to be created while still retaining the low pressure drop characteristic of the panel configuration of the steam reforming reactors. In addition, the performance of a series of reactors is improved by incorporating a mixing process into the joint pieces used between panels to form the structure.
