Patent number: 7426935Abstract: 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.Type: GrantFiled: April 14, 2005Date of Patent: September 23, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Mirko Schwan, Holger Winkelmann, Wolfgang Oelerich
