Abstract

L’invention porte sur un système électrochimique adapté à fonctionner en dépression vis-à-vis d’une pression de référence, comportant : une pile à combustible 2, une ligne d’alimentation Lad reliant une entrée Ed d’oxygène à la pression de référence à l’entrée Ce de la pile 2, une ligne d’évacuation Led reliant la sortie Cs de la pile 2 à une sortie Sd ; un réducteur de pression 6 disposé sur la ligne d’alimentation Lad et adapté à imposer à l’oxygène le traversant une pression inférieure à la pression de référence ; une pompe 3 disposée sur la ligne d’évacuation Led de sorte qu’en fonctionnement en dépression l’oxygène circule à partir de l’entrée Ed jusqu’à la sortie Sd, la pression d’oxygène à l’entrée Ce de la pile 2 étant en dépression vis-à-vis de la pression de référence. Figure pour l’abrégé : Fig. 2
