The invention relates to fuel cells (14, 22, 42) which are operated with damp operating gases (4, 53). Condensed water (6, 5, 54) condenses out as the operating gas flows from the damping device (3) to the fuel cell block (1, 21, 41). The condensed water (6, 25, 54) runs into the fuel cells (21, 452) and impairs their operation. The invention provides a fuel cell block (1, 21, 41) which has a condensed water separator (6, 25, 43). Said separator is connected to the operating gas delivery line (2, 23, 51) and prevents the condensed water (6, 25, 54) from flowing into the fuel cells (22, 42).
L'invention concerne des cellules électrochimiques (14,22,42) fonctionnant avec des gaz de fonctionnement humides (4,53). La condensation (6,25,54) de l'eau s'effectue lorsque le gaz (4,53) s'écoule de l'humidificateur (3) jusqu'au bloc de cellules électrochimiques (1,21,41). Cette eau condensée (6,25,54) parcourt les cellules électrochimiques (22,42) altérant ainsi leur fonctionnement. Selon l'invention, le bloc de cellules électrochimiques (1,21,41) présente un séparateur d'eau condensée (6,25,43) qui est raccordé à une conduite d'amenée de gaz de fonctionnement (2,23,51) et qui empêche l'écoulement de l'eau condensée (6,25,54) dans les cellules électrochimiques (22,42).
