AbstractToday s concern regarding limited fossil fuel resources and their contribution toenvironmental pollution have changed the general trend of its use and utilization to highefficiency power generation facilities like fuel cells According to annual reducing capitalcost of these utilities their entrance to commercial level is completely expected Hot gasesin Solid Oxide Fuel Cells SOFC exhaust have a useful potential in heat recovery systemsspecially for cooling and domestic hot water demands In the present thesis a SOFC withthe capacity of 215 kW has been combined with a recovery cycle in order tosimultaneously providing of electrical cooling load and domestic hot water demand of ahotel with 4600 m2 area It has been evaluated by energy and exergy analysis seeking forexergy losses and second law efficiency in each component The effect of fuel and air flowrate and also current density as controlling parameters of fuel cell performance have beenstudied 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 incomparison with common residential power and energy systems has been done General results show that based on fuel lower heating value the maximum efficiency of83 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 exergyin this cycle
