  • Hydrogen fuel cell stack and method for upgrading a hydrogen fuel cell stack
    Patent number: 11276869
    Abstract: This disclosure relates to a hydrogen fuel cell stack with one or more hydrogen fuel cell (102) having in turn a proton exchange membrane (104), a hydrogen reaction layer (112) and an oxygen reaction layer (116) within a pair of bipolar plates (106). At least a bipolar plate (106) comprises a channel (108) inside for hydrogen inflow. Additionally, this disclosure relates to a method of upgrading a hydrogen fuel cell stack, said method comprising inserting a channel (108) for hydrogen inflow inside at least a bipolar plate (106).
    Type: Grant

  • UAV take-off method and apparatus
    Patent number: 9708077
    Abstract: A method and apparatus for launching unmanned air vehicles (UAVs) includes supporting the unmanned air vehicle on a surface vehicle, such as a dolly cart, for riding along a surface such as ground or water. A towline is connected to the surface vehicle and the towline is pulled to force the unmanned air vehicle in a forward direction at a speed sufficient for take-off. The towline may be pulled by a winch system. In some embodiments the UAV is positioned with a nose down angle on the surface vehicle. The nose down angle permits overspeed of the UAV and cart as it is pulled along the ground, as well as controlled take-off.
