Abstract
A method for controlling the pressure on the cathode side of a fuel cell system is disclosed. The fuel cell system has at least one fuel cell, an air conveying device which is arranged on a common shaft with an expander, and a system bypass which connects the pressure-side outlet of the air delivery device to the pressure-side inlet of the expander via a system bypass line and a system bypass valve. The system bypass valve is opened in order to increase the pressure in the fuel cell.
