Abstract
A pressure regulator for a fuel cell unit includes a membrane that separates the pressure regulator into an anode-side region and a cathode-side region. The membrane is acted in the anode-side region by the pressure of the anode side of the fuel cell unit and in the cathode-side region by the pressure of the cathode side of the fuel cell unit. The pressure regulator further includes an actuator connected to the membrane, wherein the actuator sets a predetermined pressure on at least one of the anode and cathode sides.
