The operating design point for a PEMFC of 500cm2 is 750mAcm2

The operating design point for a PEMFC of 500cm2 is 750mA/cm2 with an air stoichiometry of 1.8 with dry inlet air at 250kPa. Determine and plot temperature vs. pressure drop required to ensure all the product water is removed by the cathode gas stream in the temperature range [20-90 °C ].
Interpret the result at 90 °C.
