Abstract
A fuel cell arrangement has an anode connected to an H2 inflow and a cathode connected to an O2 inflow. A differential pressure control device is arranged between the H2 inflow and the O2 inflow for controlling a differential pressure between the H2 inflow and the O2 inflow. The differential pressure control device has a fluid connection between the H2 inflow and the O2 inflow, in which a deflectable diaphragm is arranged, to which a pin is coupled, which, when the diaphragm is deflected, opens a valve arranged in the H2 inflow.
