The invention relates to a method for operating a fuel cell system, in particular a PEM fuel cell system, in which an anode gas is fed to an anode (1) of a fuel cell via a supply path (2) and is returned via a recirculation path (3) connected to the anode (1) using hydrogen as the anode gas. According to the invention, while the fuel cell system is starting, the anode gas is fed to a drying device (4), in particular an adsorber, via at least one normally open valve (8, 9, 10), and water is removed from the anode gas with the aid of the drying device (4). The invention also relates to a fuel cell system, in particular a PEM fuel cell system, which is suitable for carrying out the method. |
