  • Patent number: 8038029
    Abstract: A pressure vessel for storage of a pressurized fluid is provided. The pressure vessel includes a composite layer having an outer surface and an inner surface. The inner surface defines an internal cavity. The pressure vessel further includes at least one pressure relief device in fluid communication with the internal cavity. At least one thermally conductive element is continuously wound on the outer surface of the composite layer and adapted to carry load and transport heat from a heat source adjacent the composite layer to the at least one pressure relief device. A method for producing the pressure vessel is also provided.

  • Patent number: 7426935
    Abstract: A master/slave tank system for storing a compressed hydrogen gas, where the system employs an electrically driven shut-off valve for each tank in the system. The tank system includes a master tank and a slave tank for storing the gas. A first line is coupled to the master tank for providing the gas stored therein to a fuel cell stack. A master tank shut-off valve is positioned in the first line between the master tank and a pressure regulator. A second line is coupled to the slave tank for providing the gas stored therein to the master tank as the pressure difference between the slave tank and the master tank changes. An electrically driven slave tank shut-off valve is positioned within the second line, where the slave tank shut-off valve automatically closes the second line in response to an increase in the differential pressure across the slave tank valve.
