Abstract

L'invention concerne un procédé de régulation d'une humidité régnant dans un système pile à combustible PEM, en particulier une partie cathode d'un système pile à combustible PEM, d'un véhicule à moteur, un débit massique cathodique étant régulé. Ledit procédé est caractérisé en ce qu'un débit massique cathodique est réduit lorsque le véhicule à moteur fonctionne avec une charge minimale pendant une durée prédéfinie. L'invention concerne en outre un système pile à combustible PEM et l'utilisation d'un tel système pile à combustible PEM.
