A turbine () receives a flow of gas under pressure from the fuel cell and is mechanically coupled to the first compressor in order to drive it. A second compressor () of a circuit for use in flight to feed pressurized air to the aircraft cabin () is mechanically coupled to a shaft of the turbine. An electric machine () may be coupled to the same turbine shaft as drives the compressor (), the electric machine being capable of operating as a generator or as an electric motor.
