In order to relieve the power supply system of commercial aircraft of one absolutely essential load, specifically the galley with its heating and cooling appliances, said appliances are provided with at least one autonomous power supply device which can be handled without any problems and is installed in a galley trolley (1) of standardized dimensions, preferably with a fuel cell (2) together with its fuel tanks (3, 4) and voltage converters (5) in order to be replaced at the same time by means of catering lifting loaders in the course of galley supply and disposal. Instead of or in addition to this, an autonomous, mobile power supply unit such as this can also be installed in one of the standardized baggage or cargo containers for accommodation in the cargo bay of the aircraft, and then in particular also feed electrical heating and cooling appliances in other containers. |
