Abstract
The invention relates to a fuel cell arrangement () having at least one fuel cell () with a cathode () and an anode. The cathode () and the anode each have a reactant feed () and a reactant discharge (), a humidifying device () and sensors () being provided at least at one of the reactant feeds (). In particular, the sensors () are at least one fluid mass sensor () and two pressure sensors (), the fluid mass sensor () and one of the pressure sensors () being arranged upstream of the humidifying device () and one of the pressure sensors () being arranged downstream of the humidifying device (). The humidifying device () can be operated in a controlled manner on the basis of the measurements of the sensors (). The invention further relates to a method for controlling the humidity of a reactant for such a fuel cell arrangement ().
