Abstract

A fuel cell (10) has a compressed air inlet fed by a compressor (20) and a fuel inlet, and it produces direct current electricity. A turbine (30) 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 (46) of a circuit for use in flight to feed pressurized air to the aircraft cabin (40) is mechanically coupled to a shaft of the turbine. An electric machine (50) may be coupled to the same turbine shaft as drives the compressor (46), the electric machine being capable of operating as a generator or as an electric motor.
