Method for operating a fuel cell system which can be used in a vehicle, and associated fuel cell system

摘要

A fuel cell system is operated by a supply of fuel and air. The air provides the oxygen required for the operation of the fuel cells in the form of an oxidant. The invention aims to prevent the fuel cell module from damage that might be caused when the motor vehicle is operated in different environments with possibly high pollution levels. To this end, the air is purified before it is supplied to the fuel cell system by way of an air purification device that is associated with the fuel cell module.
