Abstract: Autonomous trolleys include an integrated power source, which energy can be utilized for integrated trolley systems such as a wheel assist module, heating module, and cooling module. The power source may include a fuel cell system or a rechargeable electrical energy storage device or a combination thereof. The rechargeable electrical energy storage device can be charged by any other power source, including a fuel cell system. The trolley can also be equipped with a fuel tank for easy and safe refueling of a fuel cell system.

Abstract: An area on board of a vehicle, in particular of an airplane. The area has a compartment and an opening providing access to the compartment. The area includes a curtain arranged to be drawn in a closed position in which the curtain covers the opening. The curtain includes at least one magnetic curtain element provided along a lower edge of the curtain, and the area includes at least one magnetic opening element positioned along a lower edge of the opening, which at least one magnetic opening element and at least one magnetic curtain element are arranged to attract each other when the curtain is in the closed position.
