This paper explores how the operating pressure of an evaporatively cooled fuel cell influences the required radiator frontal area via the use of a fuel cell vehicle model with validated electrochemical and radiator subsystems. Results show an operating pressure increase of 0.6 bar reduces required radiator frontal area by up to 30% at 25 kW net electrical load due to elevated operating temperatures. The influence of vehicle speed and fan speed are studied, at 25 kW net load, 0.2 bar back pressure the vehicle would overheat below 20 m/s, with 2000 rpm fan speed sufficient cooling is obtained with a 0.2m2 radiator area at all speeds.
