This paper addresses the topic of the conceptual design of a regional aircraft with hybrid electric propulsion based on hydrogen fuel *** aims at providing an optimization-based method to design a hybrid propulsive system comprising two power sources(jet fuel and hydrogen)for the generation of the required propulsive power and at studying the impact of fuel cell technologies on the aircraft ***,by performing optimizations for two hybrid propulsive systems using either low temperature or high temperature proton-exchange membrane fuel cells,this study provides a preliminary assessment of the impact of the fuel cell operating temperature on the system design and the overall aircraft ***,this paper gives a description of the baseline turboprop regional aircraft with a focus on its high speed and low speed flight performances which will serve as requirements for the design of the hybrid ***,the hybrid electric architecture and the sizing models of the propulsion system are ***,optimizations are performed to design two parallel hybrid propulsive systems based on different fuel cells technologies and aimed at minimizing the block fuel per passenger over a mission of 200 n *** show how the proposed methodology and models lead to design two propulsive systems capable of reducing the fuel consumption per passenger by more than 30%compared to the baseline *** study also shows that the choice of fuel cell operating temperature has a first-order impact on the total mass.
