Abstract: The tailgate (1) or rear door for a motor vehicle with a rear window includes a single-piece main carrying structure (10) with a peripheral, flexurally resistant frame (11), with an upper transverse beam (12), two lateral longitudinal beams (13, 14) and at least one lower transverse beam (15). The main carrying structure consists of a fibre-reinforced moulding compound (20) with at least two impregnated, integrated continuous-fibre bands (21) and this moulding compound is non-positively connected to the rear window (2) and together with this forms a flexurally resistant structure. Thereby, the continuous-fibre bands (21) in sections are integrated into the frame (11) in an arrangement vertical (v) to the surface (H) of the tailgate, by way of the continuous-fibre bands (21) being arranged vertically to the surface (H) and/or at a vertical distance (d) to the surface (H).

Abstract: The method enables the series production of light structural components out of long-fiber thermoplastic material (LFT) with integrated continuous fiber (CF)-reinforcements in a single stage LFT-pressing step. In this, CF-tapes (5) are melted open and transferred into a profile tool (21) of a CF-profile forming station (20), there are pressed for a short time period and shaped into the required CF-profile (10). In doing so, by means of contact with the thermally conditioned profile tool (21) on the profile surface (11) a shock-cooled, dimensionally stable, thin casing layer (12) is formed and the inside of the CF-profile remains melted. Following a defined short shock-cooling period (ts), the CF-profile (10) is transferred into an LFT-tool (31) and pressed together with an introduced molten LFT-mass (6). In doing so, the casing layer (12) is melted open again on the surface (11) and is thermoplastically bonded together with the surrounding LFT-mass.

Abstract: Abstract of the Disclosure A structural component (1) is made out of long- fiber reinforced thermoplastic material (LFT) with integrated continuous fiber (CF) – reinforcement. It includes at least three individually integrated, shaped CF - profiles (10), which form a three-dimensional intersection point (50). In this, at least one CF - profile (10) lies in an upper plane (H1), at least one CF-profile lies in a lower plane (H2) of the intersection point and at least one CF - profile extends continuously in a vertical direction (v) between these CF - profiles of the upper and of the lower main plane. The CF - profiles (10) are connected to one another by shapings (32) of the LFT - mass (6) at the intersection point in a force-transmitting manner. At several points loads (L) are exerted on the CF - profiles. Such three-dimensionally applied loads (L) are capable of being optimally supported.

Abstract: The method for operating a fuel cell battery (1) comprises an analysis of an integrity state of the battery. This integrity state is determined by means of measurement of operating parameters and a programmed evaluation of the measurement data. The battery is controlled for the purpose of reliable operation in such a manner that the maximum electrical output power is subjected to a limitation which is dependent on the integrity state or an interruption of the operation is initiated. The integrity state can be characterized by at least two parameters, in particular a parameter pair Cj, dj. From a relationship which contains the parameters an internal electrical resistance (Ri) of the battery can be calculated on the one hand and a statement on the quality of the battery can be derived on the other hand.

Abstract: The method for the operation of fuel cell battery (10) comprises a control system (14), through which the electrochemical reactions in cells (11) of the battery are influenced. Gaseous flows (1, 2) of two educts (A, B) are fed into the battery in a controlled manner in a conditionally predetermined ratio of quantities and are passed through the cells separately. The first educt (A) contains oxidizing components, the second educt (B) contains reducing components and the first educt is in particular ambient air. The educt flows (1, 2) are united after passage through the cells and are further treated by means of an afterburning process and with the production of a flow (3) of exhaust gas (C), so that at the conditionally predetermined ratio of quantities the reducing components are completely oxidized. The first educt flow, in particular the air flow, is variable through the control system to a limited extent; it is used for a regulation of the reaction temperature.

Abstract: To provide thermal relief, particularly of the edge of disk-shaped gate-turn-off GTO thyristors (GTO) as are used in converters in power electronics, at least one cooling segment which is isolated from a GTO cathode metallization of the GTO thyristor segment (GTO) by a gate electrode metallization of a gate electrode is arranged on the edge and laterally adjacent to the GTO thyristor segment (GTO). An insulation layer is provided between a cooling segment metallization and the gate electrode metallization. Cooling segments in an lo outer annular zone can be alternately arranged with GTO thyristor segments (GTO) or offset towards the outside in the radial direction or perpendicular direction thereto. Instead of cooling segments, a p.sup.+ -type GTO emitter layer of the GTO thyristor segments (GTO) can be shortened at the edge in the outer annular zone.
