The invention discloses a fuel cell and gas turbine hybrid power generation system, and relates to the technical field of hybrid power generation, and the system comprises a fuel cell unit used for generating electric energy through an electrochemical oxidation reaction; and the waste heat recovery unit is connected with the waste gas discharge port of the fuel cell unit and is used for treating the discharged waste gas of the fuel cell unit and recovering heat energy. The working efficiency of the fuel cell is improved, the temperature gradient of the fuel cell is reduced and'carbon deposition 'is prevented by designing anode and cathode dual circulation, and waste heat at different temperatures generated by the fuel cell and a gas turbine system is recycled by combining Brayton power cycle power generation, so that gradient utilization of energy is realized. Meanwhile, high-concentration CO2 is separated and recycled, greenhouse gas emission is reduced, and the device has the advantages of being high in use operability, flexible in operation mode, remarkable in energy-saving and carbon-reducing effect and the like.
