Fuel cell, especially molten carbonate fuel cell(MCFC), is the most promising power generating technique in 21th century. The principle of molten carbonate fuel cell power system is introduced. The development of the system, such as the improvement of cell components including electrodes and electrolyte, the fuel processing, the heat recovery, the power conditioning and grid interconnection, the control and optimization of cell parameters including pressure, temperature, reactant gas composition and utilization, and the humidity of fuel gas are also described. In addition, the present research by American, Japan and domestic organizations or corporations are presented. Natural gas fueled externally reformed MCFC system and internally reformed system are presented respectively. Moreover, the problems faced by MCFC, such as operation life, capital cost, operation cost, system miniaturization, mending electricity output, etc., are indicated. A natural gas fueled multi stage MCFC power system is given.
