    摘要： The invention relates to a fuel cell stack (10) of a fuel cell system that is to be hermetically sealed off from the environment after operation is ended so that only a finite amount of air oxygen remains in the fuel cells, thus preventing the fuel cells from excessively aging. According to the invention, locking means (26, 28; 32, 34) are provided that are disposed on or in an end plate (14) or distributor plate of the fuel cell stack (10). The locking means (26, 28; 32, 34) are therefore thermally coupled to the end plate (14) and may freeze up at cold ambient temperatures. In a preferred embodiment, the locking means (26, 28; 32, 34) comprise an elastomer body (32, 34) able to cover and uncover a channel (44, 46) in the plate (14).

    摘要： A moisture exchange module has a bundle of moisture-permeable hollow fiber membranes and at least one line element for supplying a gas stream that flows through the hollow fibers in an inner flow. The at least one line element opens out into an inflow region, which is of at least approximately the same cross section as the bundle of hollow fiber membranes. According to the present invention, the at least one line element opens out into the inflow region at an angle of from 60° to 120° with respect to the longitudinal axis of the bundle of hollow fiber membranes without the longitudinal axes of the one line element and of the bundle of hollow fiber membranes intersecting one another. An annular diverter means for diverting the gas flow are provided between the cross section of the line elements through which gas can flow and the inflow region. The diverter means are arranged in such a way that an annular gap is formed, which annular gap is connected to the at least one line element and, on its side remote from the bundle of hollow fiber membranes, is connected to the inflow region.

    摘要： A fuel cell system has at least one fuel cell, a hydrogen storage tank in which hydrogen is stored at a pressure above atmospheric and which communicates via a hydrogen supply line with an anode chamber of the fuel cell. An anode circuit, via which unreacted hydrogen is able to be recirculated from a region downstream of the anode chamber into the hydrogen supply line, is provided. At least one pumping device is provided between the outlet of the anode chamber and its inlet in the anode circuit and/or the hydrogen supply line. Between the hydrogen storage tank and the anode chamber, a turbine is provided, which supplies at least a portion of the power required for driving the pumping device.
