On-board supply system and on-board galley having a fuel cell unit for use in an aircraft

Abstract

An on-board supply system (10) for use in an aircraft comprises a fuel cell unit (20) for generating electrical energy and heat energy, and at least one consumer system (100). The fuel cell unit (20) is designed to release heat energy in the form of hot air, and the consumer system (100) is designed to absorb the electrical energy and the heat energy in the form of hot air. The fuel cell unit (20) can comprise at least one low-temperature (LT) fuel cell (30) and at least one high-temperature (HT) fuel cell (40), which can both (30, 40) be designed to be regulated to their respective operating temperature in operation by means of air cooling, and an air cooling inlet (44) of the HT fuel cell (40) can be connected in fluid communication with an air cooling outlet (36) of the LT fuel cell (30).
