Abstract
A fuel cell system (1) including at least one fuel cell (2) having a cathode area (3) and an anode area (4) is disclosed. The cathode area (3) and the anode area (4) have feed conduits (31, 41) and discharge conduits (32, 42). Downstream of the anode area (4) and the cathode area (3), a junction (12) of the discharge conduits (32, 42) is provided. The junction (12) fluidically communicates with an area (13) which includes a material that is catalytically active with respect to a reaction of a fuel for the fuel cell (2) with an oxidant for the fuel cell (2). The feed conduit (31) leading to the cathode area (3) is configured in such a manner that it fluidically communicates with the cathode area (3) in at least two different sites (19, 20) in each of the fuel cells (2). A humidifying device (16) is provided in the feed conduit (41) leading to the anode area (4).
