1. A fuel cell and heat engine hybrid system comprising:

  • a high-temperature fuel cell including an anode compartment adapted to receive fuel from a fuel supply path and to output anode exhaust gas and a cathode compartment adapted to receive oxidant gas and to output cathode exhaust gas;

    a heat engine assembly adapted to receive oxidant gas and a further gas comprising one of anode exhaust gas and a gas derived from anode exhaust gas and to cause oxidation of said further gas and generate output power, said heat engine also generating heat engine exhaust including oxidant gas, andwherein said heat engine exhaust is used to provide oxidant gas to said cathode compartment of said fuel cell.
