| Popis: | In this study, energy and exergy analyses of a 1 kW Horizon H-1000 XP Proton Exchange Membrane (PEM) Fuel Cell has been investigated. A testing apparatus has been established to analyze the system efficiencies based on the first and second laws of thermodynamics. In this mechanism pure hydrogen has been directly used as a fuel in compressed gas formation. Purity of hydrogen was above 99.99%. The system performance was investigated through experimental studies on energy and parametric studies on exergy by changing the operating pressure and operation temperature. The results showed that the energy efficiency of PEM fuel cell is 45.58% for experimental study and 41.27% for parametric study at full load. Also, 2.25% and 4.2% performance improvements were obtained by changing the operating temperature ratio (T/T0) from 1 to 1.2 and operating pressure ratio (P/P0) from 1 to 2, respectively. © 2018 Hydrogen Energy Publications LLC FBA-2018-9994 The authors would like to thank the Çukurova University Scientific Research Project Coordination ( FBA-2018-9994 ) for financial support.
