  • Fuel cell system controller
    Patent number: 8563188
    Abstract: A fuel cell system that includes a control system for regulating the power produced by the fuel cell system. The fuel cell system includes a fuel cell stack adapted to produce electrical power from a feed. In some embodiments, the fuel cell system includes a fuel processing assembly adapted to produce the feed for the fuel cell stack from one or more feedstocks. The control system regulates the power produced by the fuel cell system to prevent damage to, and/or failure of, the system.
    Type: Grant
    Filed: March 7, 2012
    Date of Patent: October 22, 2013

  • Methods for operating a fuel cell system under reduced load conditions
    Patent number: 7846569
    Abstract: Methods for operating a fuel cell system under reduced load conditions. The fuel cell system includes a control system for regulating the power produced by the fuel cell system. The fuel cell system further includes a fuel cell stack adapted to produce electrical power from a feed. In some embodiments, the fuel cell system includes a fuel processing assembly adapted to produce the feed for the fuel cell stack from one or more feedstocks. The control system regulates the power produced by the fuel cell system to prevent damage to, and/or failure of, the system. The methods include selectively diverting at least a portion of the feed from delivery to the fuel cell stack if an applied load is less than the currently available power output of the fuel cell system.
