To improve a processing system for liquid hydrogen comprising a storage t and a supply unit arranged outside of and connected with the storage tank via a suction line, the supply unit comprising a feed pump which communicates on its pressure side with a motor feed line, such that the feed pump is constantly kept at operating temperature, it is suggested that the supply unit comprise a cool-stage casing completely surrounding the feed pump, the casing having hydrogen flowing through it which exits from the feed pump on the pressure side.
