Therefore, this investigation finds that a higher cell temperature increases the membrane conductivity and the exchange current density with an improvement of the cell efficiency. An increase in the reactant saturation temperature also leads to a better performance of the fuel cell [13, 14]. Moreover, a semiempirical model based on a thermodynamic approach in order to view the effect of different parameters such as pressure, temperature, anode and cathode channel depth, and air stoichiometry on the performance of the PEMFC and the exergy efficiencies and irreversibilities of the cell. It is found that with the increase in cell operating temperature and pressure, the cell performance was ameliorated, exergy efficiency of the cell increases and irreversibilities decrease<br>
