Abstract
The method for supplying power from a fuel cell detects a sulphur oxide in the oxidising gas of the cell and decreases the operating temperature of the cell when the quantity of sulphur oxide detected is greater than a predetermined threshold. The temperature decrease can vary according to the degradation rate of the performances.
