METHOD FOR AVOIDING ICE PRESSURE DAMAGE IN WATER-FILLED COMPONENTS OF A FUEL CELL SYSTEM

摘要

The invention relates to a method for operating a fuel cell system (100) with a cathode path (10), wherein the cathode path (10) serves to provide air (L) to the fuel cell system (100), and wherein a water provision system for humidifying the air is provided in the cathode path (10) in order to keep a membrane of the fuel cell system (100) moist. To that end, it is provided, according to the invention, that the method involves at least a following step: - emptying and/or venting the water provision system.
