FUEL CELL ARRANGEMENT AND METHOD FOR OPERATING A FUEL CELL ARRANGEMENT

摘要

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).
