The invention relates to a fuel cell arrangement (1) comprising a plurality of fuel cells arranged in a protective housing (4). The inventive arrangement is embodied in such a way that it has a long service life and is highly reliable. According to the invention, the inner area (6) enclosed by the housing (4) is connected on the gas side to a closed recirculation circuit (8). A plurality of gas purifying elements are connected advantageously to the recirculation circuit (8) and used to remove water-containing components or components which would otherwise be harmful for built-in elements inside the protective housing (4) from the gas flow (G) which is conducted inside the recirculation circuit (8).
L'invention concerne un ensemble de piles à combustible (1) qui comprend une pluralité de piles à combustible disposées dans un boîtier protecteur (4). L'objectif de l'invention est de concevoir un tel ensemble qui, tout en présentant une fiabilité de fonctionnement plus élevée, soit d'une plus grande durabilité. A cet effet, l'espace intérieur (6) entouré par le boîtier de protection (4) est, selon l'invention, raccordé, côté des gaz, à un circuit de recirculation (8) fermé. Dans ce circuit de recirculation (8) est, de façon avantageuse, montée une pluralité d'éléments de purification de gaz qui sont conçus pour retirer, du courant de gaz (G) conduit dans le circuit de recirculation (8), les composants contenant de l'eau, ou autres, risquant d'endommager les pièces montées dans le boîtier protecteur (4).
