Abstarct: In this study, a molten carbonate fuel cell (MCFC) is modeled. The MCFC produced 3055 Kw and 2454 Kw electricity and heat respectively. Due to the fact that in most systems, cool water is used for cooling, the above-mentioned fluid was used for cooling the fuel cell and the output water was fed into a single effect absorption chiller in order to produce cooling load. Modeling results showed that the efficiency of fuel cell and absorption chiller were 59.77% and 84%, respectively. Some of the output electricity was fed into an air-cooled chiller in order to produce cooling load. The performance coefficient of compression chiller was 3.611 and the energy efficiency of the cycle after using compression chiller was 79.88. Exergy efficiency of fuel cell, absorption chiller and compression chiller were calculated 49.77, 81.4 and 32.3 respectively. The exergy destruction of the mentioned components was 3112, 3.256 and 49.77, respectively also the exergy efficiency of the system was increased from 81.44 to 81.68 after compression chiller. By analyzing the risk and reliability of the cycle, the results show that the system will experience at least 2 failures until the end of its working life. Economic analysis of the system showed that the PB on the system is 3.5 years.
