    • A fuel cell stack comprising a plurality of fuel cells which are connected together. Each cell has an anode, a cathode, and a membrane therebetween and which are each arranged between two bipolar plates. The anode sides of the individual fuel cells have flow fields for a gaseous fuel supplied to the fuel cells extending between an anode space arranged at the top in the fuel cell stack and an anode space arranged at the bottom of the fuel cell stack. A collecting container is provided in the anode space arranged at the bottom of the fuel cell stack for water which is produced during the electrochemical reaction and is present in the form of a liquid and the water which is collected there has an evaporation surface and serves for the humidification of the fuel fed to the fuel cell stack.
    • 一种燃料电池堆,包括连接在一起的多个燃料电池。 每个电池在其间具有阳极,阴极和膜,并且各自设置在两个双极板之间。 单个燃料电池的阳极侧具有供给燃料电池的气体燃料的流场,该燃料电池在布置在燃料电池堆的顶部的阳极空间与布置在燃料电池堆的底部的阳极空间之间延伸。 集电容器设置在布置在电化学反应期间产生的水的燃料电池堆的底部的阳极空间中,并且以液体的形式存在并且收集在其上的水具有蒸发表面并且用于 供给到燃料电池堆的燃料的加湿。
