1. A fuel cell distribution system for controlling power being applied to a system load, said system comprising:

  • a fuel cell, said fuel cell generating a draw current;

    a power conditioning module responsive to the draw current, said power conditioning module conditioning the draw current and applying the conditioned draw current to the system load;

    a fuel cell sensor, said fuel cell sensor measuring the draw current from the fuel cell and generating a fuel cell signal indicative of the measured draw current; and

    a fuel cell controller responsive to the fuel cell signal, said fuel cell controller operating a load following algorithm that defines a command signal applied to the fuel cell that sets the available output power from the fuel cell, said load following algorithm also defining a maximum current draw signal applied to the power conditioning module that defines a maximum draw current to be drawn from the fuel cell.
