    摘要: A fuel processor system contains an autothermal reactor (ATR) that produces a hydrogen-rich first gas stream containing carbon monoxide. Downstream of the ATR, a pressure swing adsorber produces a second hydrogen-rich gas stream containing 5 ppm carbon monoxide or more. Downstream of the PSA, there is a methanation reactor sized to reduce the CO level of the second stream below 5 ppm. A method of operating of proton exchange membrane fuel cell stack involves cooling the methanator output and feeding it into the stack as an anode fuel.

    摘要: A system and method for improving air humidification for fuel cell applications includes a fuel cell stack having a cathode inlet and a cathode outlet. The cathode inlet receives an oxidant. A humidifier humidifies the oxidant prior to delivery of the oxidant to the cathode inlet. An injection nozzle is provided, and a volume of water substantially vaporized by the injection nozzle reduces a temperature of the oxidant and increases a water transfer rate of the humidifier. The injection nozzle can be positioned either directly upstream of the humidifier in the oxidant inlet line or in a stack cathode outlet line which is directed into the humidifier.

    摘要: A fluid delivery device for an electrochemical conversion assembly. In one embodiment, the electrochemical conversion assembly is a fuel cell system. The device includes one or more fluid-manipulating components combined into a housing to minimize weight, size and complexity. In one form, the device may include a compressor, heat exchanger and a water vapor transfer unit, at least the latter two of which are located within a chamber defined by the housing. A controller can be used to monitor and selectively vary the extent to which at least one of these components modifies properties a fluid (such as air) that can be used as a reactant in the electrochemical conversion assembly. In a particular form, the heat exchanger and water vapor transfer unit can cooperate to promote the hydration of the reactant.
