摘要： A method and apparatus for water management in a direct oxidation fuel cell system includes a direct oxidation fuel cell, including: a housing surrounding an anode, a cathode, a protonically conductive electronically non-conductive membrane electrolyte disposed between the anode and the cathode, a current collector, and a gas-permeable liquid-impermeable membrane disposed on a side of the cathode opposite the electrolyte. Excess water accumulation is removed from an area between the membrane electrolyte and the gas-permeable liquid-impermeable membrane by a pressure differential generated, preferably by a pump. The pressure differential draws air to the surface of, into, or through the cathode diffusion layer. The pump can be driven by the electricity generated by the fuel cell.

摘要： A method and apparatus for a Boiling Water Reactor (BWR) jet pump inlet mixer support that provides rigid support for inlet mixers. The inlet mixer support attaches to a conventional BWR jet pump assembly to pull the inlet mixer away from the centerline of a riser pipe or maintain the existing inlet mixer position. The inlet mixer support may provide redundant support that may otherwise be provided by set screws of a conventional restrainer assembly. The inlet mixer support may, alternatively, be used in lieu of conventional set screws. The inlet mixer support may also counter-act additional side loading that may be applied to inlet mixers to stabilize inlet mixer movement and vibration when the BWR jet pump assembly is in operation. Optionally, the inlet mixer support may also prevent removal of existing restrainer bracket set screws.

摘要： A single pump fuel cell system is provided that has multiple valves that have selective positioning to control fluidic flow throughout a fuel cell system. One of the valves provides for high and low concentration fuel dosing. Another valve or series of valves controls an unreacted fuel recirculation loop leading from the fuel cell. Another valve or series of valves control condensate collection by the fuel cell system, and allows the purging of the anode recirculation loop. Each of the valves is selectable between various positions to place the fuel cell system in a desired operating mode. A heat exchanger may also be employed to dissipate heat as desired out of the fuel cell system. A concentration sensor can also be employed to aid in achieving a desired fuel concentration within the fuel cell system.

摘要： The present invention is directed to a novel anode plate forming an anode chamber of a fuel cell. The anode plate includes an anode fuel flow field, a substantially gas permeable membrane, and a channel coupled to an outlet positioned immediately adjacent the membrane. The channel directs gaseous effluents produced in the anode chamber out of the fuel cell via the outlet. This novel anode plate may be used in a single fuel cell, electrically and mechanically coupled to a cathode plate in a multi-fuel cell arrangement, or combined with a cathode plate producing a bi-polar plate for a fuel cell stack. Alternatively, the features of the anode plate and cathode plate may be integrated into a single component, thus improving performance and limiting the size of a stack and system implementing the stack.
