  • Patent number: 8263259
    Abstract: Bipolar plates and end plates for fuel cell stacks. The bipolar plates or end plates may include semi-conductive or conductive bodies, intricate features with close tolerances such as narrow flow channels and conduits with complex flow paths, integral resistive heating elements, internal catalytic reforming capability, integral heat exchanging structure, substantially flat and undistorted contact faces, integral sensors, and internal recuperative heat exchanging capacity. Methods of making bipolar plates and end plates for fuel cell stacks. The methods involve a range of integrated processing techniques that enable a flexible approach to bipolar and end plate design. In addition, the ability to reliably produce features on a small scale allows for the potential miniaturization of bipolar plates and end plates and is therefore ideally suited to further the development of small scale portable fuel cell systems.

  • Patent number: 8088506
    Abstract: The invention is an electrochemical battery cell with a fluid consuming electrode, such as an oxygen reduction electrode, and a fluid regulating system. The fluid regulating system includes a valve for adjusting the rate of passage of the fluid to the fluid consuming electrode. It is operated by an actuator that responds (e.g., by deforming) to changes in a potential applied across the actuator to open or close the valve. The applied potential can be the cell potential or an adjusted potential. The potential applied across the actuator can vary according to the need for more or less fluid in the fluid consuming electrode. The valve can be contained within the cell housing, for example between the fluid consuming electrode and one or more fluid entry ports in the cell housing, or it can be located outside the cell housing.
