Abstract
In this work, the performance of a hydrogen-electric powertrain for regional aircraft is analysed. The analysis is based on experimental and modelling results of the DLR-owned ground-based BALIS powertrain with up to 1.2 MW maximum power output consisting of an LH2 tank with a storage capacity of 200 kg, a fuel cell system of 12 polymer electrolyte membrane fuel cell modules in a 2s6p configuration, and an e-drive system of two permanent magnet synchronous machines connected mechanically with a summation gear. The results indicate that the subsystems work properly and substantiate the feasibility of LH2/PEMFC electric powertrains in the MW range.
