Title (EN) FUEL CELL SYSTEM
(FR) SYSTÈME À PILE À COMBUSTIBLE
Abstract:
(EN) The invention relates to a fuel cell system comprising a stack of electrochemical cells forming a fuel cell (6) having a polymer ion exchange membrane, a fuel gas supply circuit and an oxidizing gas supply circuit. Said oxidizing gas supply circuit comprises a compressor (3) designed to compress the ambient air prior to entry into the fuel cell (6), and an exhaust outlet (10) designed to evacuate the gases exiting from the fuel cell. Said supply circuit is connected to the fuel cell at a first (7) and a second (8) access point. The system is characterized in that it further comprises a switching element (11) having two positions: a first position in which the compressor (3) outlet is connected to the first access point (7) and the second access point (8) is connected to the exhaust outlet (10), and a second position in which the compressor outlet (3) is connected to the second access point (8) and the first access point (7) is connected to the exhaust outlet (10).
(FR) L'invention concerne un système à pile à combustible comprenant un empilement de cellules électrochimiques formant pile à combustible (6) à membrane polymère échangeuse d'ions, un circuit d'alimentation en gaz carburant et un circuit d'alimentation en gaz comburant. Ledit circuit d'alimentation en gaz comburant comprend un compresseur (3) destiné à compressé l'air ambiant avant son entrée dans la pile à combustible (6), et un échappement de sortie (10) destiné à évacuer les gaz sortant de la pile à combustible. Ledit circuit d'alimentation est relié à la pile à combustible en un premier (7) et un second points (8) d'accès. Le système est caractérisé en ce qu'il comprend en outre un élément d'aiguillage (11) possédant deux positions : une première position dans laquelle la sortie du compresseur (3) est reliée au premier point d'accès (7), et le second point d'accès (8) est relié à l'échappement de sortie (10), et une seconde position dans laquelle la sortie du compresseur (3) est reliée au second point d'accès (8), et le premier point d'accès (7) est relié à l'échappement de sortie (10).
