  • Technique to regulate an efficiency of a fuel cell system
    Patent number: 7166379
    Abstract: A technique that is usable with a fuel cell stack includes providing a fuel flow to the stack, changing the fuel flow and observing a response of at least one cell voltage of the stack to the change in the fuel flow. An efficiency of the stack is regulated based on the observation.

  • Controlling a fuel cell system
    Publication number: 20050136296
    Abstract: A technique that is usable with a fuel cell system includes using a stored energy source to supply power to a load, placing a fuel cell stack in an inactive state during the using, returning the fuel cell stack to an active state to recharge the stored energy source and returning the fuel cell stack to the inactive state in response to the completion of the charging. Another technique may include determining a system power demand in the fuel cell system and may include determining whether a fuel cell stack is exhibiting unstable behavior during an interval of low power demand from the fuel cell stack. In response to these determinations, the fuel cell stack is isolated from the fuel cell system. Another technique includes pulsing a fuel processor of the fuel cell system with an input reactant flow to minimize at least one of a power loss and a startup time of the fuel processor.
