    摘要: The invention relates to a method for controlling the pressure in an anode (4) of a fuel cell (1), with hydrogen (2) being fed to the anode (4) via a feed-pressure control unit (33), and oxygen (3) or air being fed to the cathode (5), and a mixture (28), which consists of a gas portion (32) and a condensate (31) being periodically discharged from the anode (4) via a discharge line (29) via a discharge-pressure control unit (34) and collected and separated in a reservoir (30), and with the gas portion (32) being fed back to the anode (4). In order to effect feedback of hydrogen (2) with minimum power consumption, it is provided that the discharge-pressure control unit (34) is opened for periodically discharging the mixture (28), and that the mixture (28) is conveyed into the reservoir (30) via the discharge line (29), with the pressure prevailing in the reservoir (30) being adapted to that in the feed means of hydrogen (2), whereupon the discharge-pressure control unit (34) will be closed and the feed-pressure control unit (33) and a feedback-pressure control unit (37) will be controlled such that the pressure prevailing in the reservoir (30) will be changed due to the own pressure consumption of the anode (4) until a desired value (41) will be reached for the pressure in the reservoir (30) and/or a preset threshold value for the pressure in the anode (4) will be reached, whereupon the feedback-pressure control unit (37) and the feed-pressure control unit (33) will be controlled such that the pressure in the anode (4) will be adapted to a preset desired value (40).

    摘要: The invention relates to a method and to a device for discharging used operating media of a fuel cell (1) in a fuel cell system (20), at least some of which are explosive, comprising a sensor unit (30) for examining the operating media discharged from an operating space (27). In order to discharge the used operating media from the fuel cell system independently of the operation of the fuel cell system and taking safety regulations into account, a mixing zone (32) is provided for mixing the operating media with a scavenging medium (28) to obtain waste air (33), wherein the operating space (27) is closed by a fan (29), and the sensor unit (30) is disposed downstream of the mixing zone (32), viewed in the flow direction of the waste air (33).

    摘要: A method for controlling the anode pressure of a fuel cell is disclosed, with hydrogen fed to the anode via a feed-pressure control unit, and a gas/condensate mixture periodically discharged from the anode via a discharge-pressure control unit into a reservoir, with the gas portion fed back to the anode. To effect feedback of hydrogen the pressure in the reservoir is adapted to that in the hydrogen feed means during discharge, whereupon the discharge-pressure control unit is closed and the feed-pressure control unit and a feedback-pressure control unit are controlled such that the pressure in the reservoir changes due to consumption at the anode until a desired pressure in the reservoir is reached and/or a preset pressure in the anode is reached, whereupon the feedback-pressure control unit and the feed-pressure control unit are controlled such that the pressure in the anode adapts to a preset desired value.
