An integrated hydrogen-electric engine includes an air compressor system 60, a hydrogen fuel source, a fuel cell 26, an elongated shaft 10 configured to drive the air compressor system and a propulsor, and a motor assembly 30 disposed in electrical communication with the fuel cell, wherein the air compressor system is connected to the elongated shaft through an engagement mechanism. The engagement mechanism preferably includes a gear box 56 and a clutch 52, for example a magnetic clutch, a hydraulic or pneumatic clutch, or a mechanical or electromechanical clutch. The engine may comprise a plurality of compressors configured to be driven by the shaft through a plurality of engagement mechanisms. A fuel cell powered airplane comprises at least one electric motor and the engine of the invention. An advantage of the invention is that the rotational speed of the compressor may be increased whilst it is being driven by the same motor and shaft as the propulsor.
