    摘要: A MEMS-based fuel cell has a substrate, an electrolyte in contact with the substrate, a cathode in contact with the electrolyte, an anode spaced apart from the cathode and in contact with the electrolyte, and an integral manifold for supplying either a fuel or an oxidant or both together, the integral manifold extending over at least a portion of the electrolyte and over at least one of the anode and cathode. Methods for making and using arrays of the fuel cells are disclosed.

    摘要: An inkjet printhead includes an inkjet nozzle with a main actuator and at least one peripheral actuator in the same firing chamber. When the inkjet nozzle has sat idle, both the main actuator and the peripheral actuator are activated to jet at least one ink drop to renew the inkjet nozzle to mitigate decap conditions. When the inkjet nozzle has not sat idle, only the main actuator is activated to jet ink drops. The ink drops jetted by activating both the main and the peripheral actuators and the ink drops generated by activating only the main actuator have the same drop weight and drop velocity.

    摘要: 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.
