Today’s concern regarding limited fossil fuel resources and their contribution to environmental pollution have changed the general trend of its use and utilization to high efficiency power generation facilities like fuel cells. According to annual reducing capital cost of these utilities, their entrance to commercial level is completely expected. Hot gases in Solid Oxide Fuel Cells (SOFC) exhaust have a useful potential in heat recovery systems specially for cooling and domestic hot water demands. In the present thesis, a SOFC with the capacity of 215 kW has been combined with a recovery cycle in order to simultaneously providing of electrical, cooling load and domestic hot water demand of a hotel with 4600 m2 area. It has been evaluated by energy and exergy analysis seeking for exergy losses and second law efficiency in each component. The effect of fuel and air flow rate and also current density as controlling parameters of fuel cell performance have been studied and a visual software for energy-exergy analysis and parametric study is provided. At the end, an economic study of simultaneous energy generation and recovery cycle in comparison with common residential power and energy systems has been done. General results show that, based on fuel lower heating value, the maximum efficiency of 83 percent for simultaneous energy generation and heat recovery cycle can be achieved. This efficiency is related to climate condition of July at 5 pm and all the electrical energy, cooling load and 40 percent of hot water demand can be provided by this cycle. About 49percent of input exergy will be efficiently used for building energy requirements. Generator in absorption chiller and SOFC are the most destructive components of exergy in this cycle.
