In this work we perform a preliminary analysis of a full electric general aviation aircraft based on fuel cells andrnwe compare the performance of this solution with those obtained with the same aircraft when powered withrnsolid state batteries. For the considered class of aircraft, the results show that the fuel cell-based system canrnachieve a much greater range with respect to the battery powered system, when constraining the maximumrntake-off weight (MTOW). In particular, the fuel cell-based solution can achieve values of the range as large asrn700nm, with a mass penalty with respect to the internal combustion engine (ICE) of about 30%, whilst thernbattery powered solution can only attain values of the range equal to 230nm
