  • Publication number: 20240429342
    Abstract: A semiconductor component having at least one emitter, at least one base, and a pn junction formed between emitter and base, having at least one non-metallic transverse conduction layer for the transverse conduction of majority charge carriers of the emitter. The emitter includes the transverse conduction layer and/or the transverse conduction layer is formed parallel to the emitter and in a manner electrically conductively connected thereto, and having a break side, at which the semiconductor component was singulated. A transverse conduction avoidance region is formed and arranged at the break side such that the transverse conductivity is reduced by at least a factor of 10, wherein the transverse conduction avoidance region has a depth (TQ) in the range of 5 ?m to 500 ?m, in particular 10 ?m to 200 ?m, perpendicular to the break side. A method for singulating a semiconductor component is also provided.

  • Publication number: 20230204050
    Abstract: The invention relates to a feed unit (1) for a fuel cell system (31) for feeding and/or controlling a gaseous medium, in particular hydrogen, comprising a jet pump (4), which is driven by a propelling jet of a gaseous medium under pressure, an outlet of the feed unit being fluidically connected to an anode inlet (5) of a fuel cell (32). The jet pump (4) has an intake region (7), a mixing tube (9) and a diffuser region (11), and the gaseous medium flows through the jet pump in a flow direction (III) which runs parallel to a longitudinal axis (52) of the jet pump (4), and the diffuser region (11) is at least indirectly fluidically connected to the anode inlet (5) of a fuel cell (32). The jet pump (4) has a housing assembly (6), the housing assembly (6) having the components main body (8) and mixing tube insert (17), resulting in particular in a modular design of the jet pump (4).

  • Patent number: 11682776
    Abstract: The invention relates to a metering valve (1) for controlling a gaseous medium, in particular hydrogen, comprising a valve housing (2), wherein an interior space (3) is formed in the valve housing (2). A reciprocating closing element (10) is arranged in the interior space (3), which interacts with a valve seat (37) for opening or closing at least one passage channel (25). Furthermore, the metering valve (1) comprises a nozzle (11), the at least one passage channel (25) being formed in the nozzle (11) and the passage channel (25) having a circular-cylindrical portion.

  • Publication number: 20220181654
    Abstract: The invention relates to a conveyor unit (1) for a fuel cell system (31) for conveying and/or controlling a gaseous medium, in particular hydrogen, comprising a jet pump (4), which is driven by a propulsion jet of a pressurized gaseous medium, and a metering valve (6), an outlet of the conveyor unit (1) being fluidically connected to an anode inlet (15) of a fuel cell (29). The jet pump (4) has a suction region (7), a mixing tube (18), and a diffuser (20), wherein the diffuser (20) is at least indirectly fluidically connected to the anode inlet (15) of the fuel cell (29), and the gaseous medium flows through the jet pump (4) at least partly in the direction of a first flow direction (V) which runs parallel to a first longitudinal axis (39) of the mixing tube (18). According to the invention, a second longitudinal axis (40) of the diffuser (20) is curved or inclined relative to the first longitudinal axis (39) of the mixing tube (18).
