The current work utilizes the waste heat of the cell exhaust in cooling systems to improve the hydrogen fuel cell efficiency. The analytical study is carried out using Engineering Equations Solver (EES) software. Simulation code, based on the laws of thermodynamics, is developed to assess performance of the Proton Exchange Membrane fuel cell (PEM) and the absorption refrigeration system. The results show that the hydrogen fuel cell is affected by the operating temperature. The voltage difference and the power of the cell increases with the increase in the operating temperature. The elevated generator temperature that is gained from the exhaust of the fuel cell enhances the performance factor of the absorption refrigeration system and the amount of cooling
