    摘要: Method of operating an autothermal reformer (ATR) to produce a high temperature reformate including preheating steam and air inputs to the ATR with heat from the reformate. The steam is heated by the reformate, and the air is then heated by the steam. There is no direct heat exchange between the reformate and the air. In the heat exchangers effecting the heat transfer, the steam is kept at a higher pressure that both the reformate and the air.

    摘要: A flow translocator disposed within a conduit for transferring and separating laminar fluid flow during translocation of the fluid core to the outer perimeter of the conduit and the outer perimeter flow to the center of the conduit. The flow translocator includes a disk disposed transverse the length of a conduit and having an outer profile conforming to the inner profile of a conduit to form a sealed fit. Arrays of slots extend about the disk for simultaneously directing the fluid core to the inner profile of a conduit and the outer perimeter flow toward the fluid core. The slots are staggered to maintain separation of the fluid core and the outer perimeter fluid during translocation.

    摘要: A model uses various operating characteristics of a fuel cell to predict the relative humidity profile that is occurring within the fuel cell as a function of the reaction progress. The model is used to predict the relative humidity profile that will occur in response to changes to one or more of the operating characteristics of the fuel cell. A high frequency resistance of the fuel cell can also be used as a measure that is indicative of the humidity within the fuel cell. The model and/or the high frequency resistance can be used in a closed-loop feedback system to control the operation of the fuel cell to maintain the humidification of the MEA and fuel cells within a desired range to achieve a desired fuel cell performance.

    摘要: A passive water drain for removal of water from a fuel cell system is disclosed, the drain including a main body having a cavity formed therein, an interior element, and a hydrophilic porous media. The passive water drain is adapted to simplify the anode reactant recycler, eliminate the need for bypass valve systems used to remove water from the cathode exhaust, and eliminate the need for condensate draining systems used for compressed air entering the cathode.
