1. An electrical system for a fuel cell hybrid vehicle, said system comprising:

  • a high voltage bus;

    a fuel cell stack electrically coupled to the high voltage bus;

    a high voltage battery electrically coupled to the high voltage bus;

    a bi-directional DC/DC power converter electrically coupled to the high voltage bus between the fuel cell stack and the high voltage battery;

    an electric traction system power inverter module electrically coupled to the high voltage bus, said power inverter module converting high voltage DC power signals from the high voltage bus to system AC power signals; and

    an electric power take out circuit including the bi-directional DC/DC power converter and the electric traction system power inverter module, said bi-directional power converter providing an external voltage signal and said power inverter module providing an external AC power signal when the electrical system is in an electric power take out mode.
