Abstract
The electrical supply system (10) of an electrical propulsion system (4) of an aircraft (1) includes: two first sets of fuel cells (FC11, FC12), configured to supply electrically an electric motor driving a propulsion propeller; a first compressor (C1) configured to supply compressed air to at least part of the at least two first sets of fuel cells (FC11, FC12); and a first electric motor (M1) designed to drive the first compressor. The first electric motor (M1) includes electrical windings (W1a, W1b), each electrical winding supplied electrically by a set of distinct fuel cells from amongst the at least two first sets of fuel cells (FC11, FC12).
