Abstract: The invention relates to a device (1) for separating and collecting water from a gas stream, comprising a water separator (2), configured as a riser, and a water tank (3) which is arranged below the water separator (2), wherein the water separator (2) has, at its lower end, an outlet (4) which opens into the water tank (3), a lateral gas inlet (5), and a gas outlet (6) which is arranged at its upper end. The invention also relates to a fuel cell system (20) with a corresponding device (1) and to a method for operating a fuel cell system (20).

Abstract: The invention relates to a humidification device (1) for a fuel cell system (2), comprising an inlet (3) and an outlet (4) for a first medium to be humidified, preferably cathode supply air, and an inlet (5) and an outlet (6) for an aqueous second medium, preferably cathode exhaust air. According to the invention, the humidification device (1) is modularly designed and has at least one module element (11, 12, 13) into which at least one shut-off valve (7, 8) and/or at least one bypass valve (9, 10) is or are integrated. The invention furthermore relates to a fuel cell system (2) having a humidification device (1) according to the invention.

Abstract: A fuel-cell system has at least one fuel cell, an oxidant line, a compressor, an exhaust-air line, a turbine, which is arranged in the exhaust-air line and is coupled to the compressor, an anode-purging line, which is connected to the exhaust-air line and has an anode-purging valve, and a control unit.

Abstract: A device (1) for measuring the injection rate dm(t)/dt of an injection valve (2) for a fluid (4a), wherein m(t) is the injection quantity of the fluid (4a) as a function of the time (t), having a measurement volume (3) which is closed off on all sides and which is filled with a test fluid (4), having an opening (5a) in one wall (5) of the measurement volume (3) for the purposes of receiving the injection valve (2) such that the injection valve (2), in the installed position, projects with at least one injection opening (2a) into the measurement volume (3), and having a pressure sensor (6) which is arranged in the measurement volume (3), wherein correction means (8, 8a, 9a, 9b, 9c) are provided for determining the propagation time of a pressure wave (12), which originates from the injection opening (2a) and which propagates through the test fluid (4), to the pressure sensor (6) and for correcting the measured injection rate dm(t)/dt, taking said propagation time into consideration, to give a rectified injectio

Abstract: An aquatic lifting device to lift a person into and out of a swimming pool or similar location, the lifting device includes a base with a mast segment coupled to and extending upwardly from the base. A pair of spaced apart support arms are pivotally coupled to the mast segment, with a transport assembly structured to support a person during pivotal movement of the support arms, secured at a first end of the support arms. A pivot assembly is provided and is structured to pivotally move the support arm relative to the mast segment so as to correspondingly raise and lower the transport assembly and the person supportably disposed thereon, and a plurality of casters are secured to the base so as to facilitate movement and re-positioning of the entire assembly.

Abstract: In a microwave apparatus for media which can be circulated and heated by high frequencies, an elongated shaft having a rectangular cross-section transverse to the elongated direction is provided at one end with a microwave transmitter. At the one end the shaft forms a hollow wave guide followed to the opposite end by a resonator chamber. The shaft has the same cross-sectional shape between its ends. A microwave permeable conductor in the form of a hairpin-shaped loop extends through the resonator chamber from the opposite end. The opposite end of the shaft is closed off by a flange plate secured to a flange on the shaft and the inlet and outlet ends of the loop are located in the flange plate.
