    摘要: A method of managing air flow for a fuel cell power system comprising, providing air expelled from a compressor and providing air expelled from a humidification device. The method further includes mixing the air expelled from the compressor with the air expelled from the humidification device upstream of a fuel cell and supplying the mixture to a cathode of the fuel cell.

    摘要: Perforated fins are provided to improve the capabilities of fin and tube type heat exchangers, and to adapt them for flow outside of the tube that is essentially parallel to the axis of the tube. The fins are made of a thermally conductive material, such as metal, with perforations in the fins. Fins can be of any shape. Typically, one or more tubes or binding posts pass through the fins. The fins are attached to the tube or post by press fitting, furnace or torch brazing, welding, or other method of mechanical bonding. The perforations allow heat exchange with the contents of a tube of a fluid flowing essentially parallel to the axis of the tube, in contrast to conventional fin-tube heat exchangers. The fins may also be bonded to a post or other securing means and inserted into the inside of a tube or other hollow body to improve efficiency of heat exchange. In addition, the fins may carry a catalyst, optionally carried on a washcoat or similar treatment to increase surface area.

    摘要: Check valves include a valve seat and a movable valve member, or piston. Movement of the piston is what allows fluid to either flow or be prevented from flowing. A magnetic check valve is provided that contains an annular piston, which is configured such that the fluid flows through a central aperture in the piston. Fuel cell systems include a cathode loop which is in contact with the proton exchange membrane (PEM). The PEM is sensitive to fowling by contaminants that may be present in the ambient air. The magnetic check valve apparatus disclosed herein prevents backflow of air through the exhaust side of the cathode loop. The valve is used on the inlet side of the cathode as well.

    摘要: In accordance with one embodiment, a method of drying a hydrogen gas mixture is disclosed. The method may include determining a mass flow rate of water {dot over (m)}H2O in a hydrogen gas mixture stream and an adsorbent capacity of one or more adsorbent beds; determining a first period of time based on the determined mass flow rate of water {dot over (m)}H2O in the hydrogen gas mixture stream and the adsorbent capacity; directing the hydrogen gas mixture stream through a first adsorbent bed of the one or more adsorbent beds for the first period of time; adsorbing a quantity of water from the hydrogen gas mixture stream into the first adsorbent bed; and regenerating the first adsorbent bed.
