Abstract

A fuel cell system (1) having a cell stack (2) for the carrying out of electrochemical reactions is provided which is provided with inlets (3a, 3b) for an oxidant (5) and for fuel gas (6) and with outlets (4a, 4b) for exhaust gases (7a, 7b). The fuel cell system (1) additionally includes an apparatus (10) having a gas-permeable structure which contains a substance which reacts with gaseous chromium species, wherein the apparatus is in communication with at least one of the outlets to direct exhaust gases through the apparatus and to separate chromium species which are carried along by the exhaust gases.
