Abstract: To produce a structural element that withstands corrosive and/or abrasive flows of hot gas during a predetermined service life and, on the other hand, can be advantageously produced, it is proposed that the structural element comprises a fiber-ceramic main body, in that the main body is formed by a C/C shaped body having a fiber-ceramic structure converted with Si to C/C—SiC in a volume region bordering on an upper side of the main body, and in that a coating comprising a metal is applied to at least a partial region of the upper side of the main body.

Abstract: To provide a seal for transported goods, comprising a carrier, by means of which the seal can be fixed to an application, signal-transmitting and/or signal-receiving components disposed on the carrier, and connection lines between components, the connection lines being disposed on the carrier, the carrier is configured in such a way that, in the event of separation from an application to which the carrier has been fixed, one or more connection lines are damaged.

Abstract: To provide a fuel cell system, comprising a fuel cell device having one or more fuel cell blocks in which chemical energy can be converted into electrical energy, an oxidant supply device for the fuel cell device, a fuel supply device for the fuel cell device, and a control device, which can be used in a versatile manner, it is provided that the fuel cell device and/or the oxidant supply device and/or the fuel supply device is/are formed as a module, the functional components of the respective device being disposed in a module, the respective module forming a unit which can be put in place as a whole, and the respective module having a communication interface which has connectors.

Abstract: A ceramic armor plate is proposed which is formed in one piece and which comprises a plurality of connected segments that are functionally separated by crack stoppers, whereby the crack stoppers serve to prevent the propagation of cracks from one segment to a neighboring segment.

Abstract: To provide a universally usable free-piston device with electric linear drive, comprising at least one piston receptacle with at least one piston device arranged for linear displacement in the piston receptacle, the piston device comprising a traveller device, and a stator device being arranged on the piston receptacle, and the at least one piston device being drivable under the action of a medium which expands in an expansion space, it is proposed that the piston stroke be variably adjustable via the linear drive such that the dead centers of the displacement of the piston device are definable.
