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.
