Given a fuel cell stack with each cell generating 1 A/cm2 and a geometric area of 150 cm2 per plate, if the air flow in the cathode inlet RH is 25% at 80C and 1.5 atm, what must the cathode stoichiometry be to remove exactly the amount of water generated by reaction as water vapor at 80C? You can assume the flow rate, pressure, and temperature are constant in the fuel cell and the exit RH is 100%.
