Abstract: Abstract: Fuel cells are energy conversion devices that can directly convert chemical energy from fuels into electricity. A cogeneration system made up of the high temperature fuel cell and the absorption refrigeration was proposed by using the waste gas exhausted from the high temperature fuel cells to drive the absorption refrigeration. In addition to supplying electricity, this system can also provide a large building with airconditioning in summer and heating in winter. Results of the energy and exergy balance analysis of the system show that the overall fuel utilization efficiency of the proposed cogeneration system is more than 86%, and the largest exergy loss is generated in the fuel cell.
