  • Patent number: 9141923
    Abstract: A fuel cell fleet has a plurality of fuel cell systems each connected to a data server. The data server may be configured to obtain operational data from of the plurality of fuel cell systems. An efficiency controller operably connected to the data server and is configured to predict an efficiency and a power output of the fleet from the operational data and optimize the efficiency of the fleet to minimize the fleet fuel consumption while maintaining a desired fleet output power. The efficiency may be determined by a ratio of the fleet output current or output power to the fleet fuel consumption.
