High temperature fuel cell system features high efficiency, environmental friendliness and enormous potential of exhaust gas waste heat utilization. The combination of this system with a gas turbine to form a hybrid power plant can well be regarded as a very promising scheme of future distributed power generation. A brief description is given of the high temperature fuel cell and the hybrid cycle system consisting of the fuel cell and a gas turbine. This is followed by a performance analysis of two typical hybrid systems (topping cycle and bottoming one). The above work can provide some informative materials and data for the development of the high temperature fuel cell and gas turbine hybrid cycle system in China.
