  • Patent number: 8354196
    Abstract: A fuel cell unit is provided having at least one fuel cell to which is connected a coolant circuit associated with a storage unit for storing and providing liquid water coolant at the fuel cell both under normal operating conditions and under frost conditions. The storage unit is set to provide a smaller amount of liquid water coolant under frost conditions than under normal operating conditions.
    Type: Grant
    Filed: December 15, 2010

  • Patent number: 7477008
    Abstract: A plasma jet spark plug for internal combustion engines includes a center electrode, a shot channel defined by insulation material, and a ground electrode concentric with the shot channel. The center electrode has a conical shape and the ground electrode defines an outlet opening of the shot channel at a distal end of the spark plug. The shot channel has a tapered shape that forms an acceleration zone for plasma that is formed near the conical tip of the center electrode as the plasma moves toward the ground electrode.
