Abstract
A method for reducing the carbon corrosion in a fuel cell stack of a fuel cell system includes the steps of detecting a corrosion value which is representative of the extent of the carbon corrosion probably occurring in the fuel cell stack during an inactive phase of the fuel cell stack, and initiating a protective measure for reducing the carbon corrosion in the fuel cell stack on the basis of the corrosion value.
