Fuel cell power plant
 A fuel cell power plant comprising a fuel cell employing a molten carbonate as an electrolyte, a reformer for reforming fuel into a reactive gas to be supplied into the anode of the cell, an expansion turbine connected to a compressor, a combustor for burning a gas exhausted from the anode and introducing the combustion gas into the cathode of the fuel cell along with a gas compressed by the compressor, and a waste heat recovery system. The power plant is characterized by the provision of another combustor on the passage through which cathode exhaust gas is sent from the cathode to the turbine and a passage for leading a part of the anode exhaust gas to the combustor, whereby unburned gas, included in the anode exhaust gas, is burned with the cathode exhaust gas supplied as oxygen source so that the temperature of the turbine driving gas is raised, as a result, the overall thermal efficiency of the power plant increases.
