Résumé
Fuel cell systems are becoming increasingly desirable for propulsion of sustainable, low emission aircraft. In this study, a fuel cell system consisting of a fuel cell stack, hydrogen storage, and a cowled radiator was sized to evaluate the performance impact of the radiator on a Diamond DA20 trainer aircraft. The fuel cell stack sizing is done by determining the total number of cells required to meet the power requirement, and the operating voltage is optimized for the lowest system mass. The drag from the radiator and its inlet cowl is determined through approximating their coefficients of drag, and the extra power required at the motor to overcome the drag is included in the sizing of the fuel cell. With a single pilot on board, the range of the aircraft had to be reduced from the target 973 km, to 690 km to meet the 254 kg mass requirement for the system. The hydrogen storage tank, fuel cell stack, and radiator represented 57.0%, 26.5%, and 8.8% of the system weight respectively. The hydrogen fuel and coolant represented the remaining 4.6% and 3.1%, respectively. The power required to overcome the drag from the radiator and cowl consumed 2.5% of the total power produced by the fuel cell during cruise. The findings indicate that the performance impact of the thermal management system should not be neglected in the preliminary performance assessment of fuel cell systems for aircraft propulsion.
