  • Fuel cell stack clamping device
    Patent number: 7776489
    Abstract: A clamping device includes an oblique device and a unidirectional load control plate disposed on the outside of the fuel cell stack, not on the inside of the fuel cell stack. The device can automatically compensating the surface pressure in the fuel cell stack to be maintained constant, and provide a large clamping load with a small force using the load of the fuel cell stack.

  • METHOD FOR FABRICATING SOLID BODY HAVING SUPERHYDROPHOBIC SURFACE STRUCTURE AND SUPERHYDROPHOBIC TUBE USING THE SAME METHOD
    Publication number: 20090260702
    Abstract: The present invention relates to a method for manufacturing a solid body having a superhydrophobic surface structure formed by using a surface treatment of a metal body, a replication process, and a polymer sticking phenomenon to increase efficiency of fluid transfer and prevent foreign materials from being accumulated in the tube, and a superhydrophobic fluid transfer tube using the method. The superhydrophobic fluid transfer tube includes a fluid guider and a solid body provided on a fluid contact surface of the fluid guider and has micrometer-scaled unevenness and nanometer-scaled protrusions.

  • Fastening mechanism of a fuel cell stack
    Publication number: 20050064268
    Abstract: A fastening mechanism of a fuel cell includes a pair of end plates for supporting the fuel cell stack by respectively being mounted to both ends of the fuel cell stack. A plurality of fastening bands elongated in an accumulation direction of the fuel cell stack pressurize the end plate by a predetermined pressure. Such a fastening mechanism enables uniform pressure on a separator and enhances sealing of a fuel cell stack.
