METHOD FOR MANAGING A FUEL CELL DURING SULFUR COMPOUND POLLUTION, AND POWER SUPPLY DEVICE

The method for managing a fuel cell having an active gas flowing in contact with an electrode includes a step of comparing the concentration of a sulfur compound in the active gas with a threshold indicative of a sulfur compound pollution phase and a step of temporary introducing an oxygenated and n...

Zusammenfassung:	The method for managing a fuel cell having an active gas flowing in contact with an electrode includes a step of comparing the concentration of a sulfur compound in the active gas with a threshold indicative of a sulfur compound pollution phase and a step of temporary introducing an oxygenated and non-sulfur polluting gas into the active gas if the concentration is higher than the threshold. The polluting gas can be introduced during or after the pollution phase.
