CA 2371257
A freeze tolerant fuel cell system and method of operating the freeze tolerant fuel cell system is disclosed. The freeze tolerant fuel cell system is realized by separating the coolant loop [25] from the active membrane [12] through the use of gaskets [20, 21] interposed between the collector cell plates [18, 19]. A method of operating the freeze tolerant fuel cell system is disclosed which comprises flowing a coolant fluid other than pure water having a sufficiently low freezing point through the coolant loop [25]. A method for startup and shutdown of the freeze tolerant fuel cell system is also disclosed.
L'invention concerne un dispositif de pile à combustible supportant le gel et un procédé d'exploitation de ce système. Le dispositif de pile à combustible supportant le gel selon l'invention est réalisé en séparant le circuit de refroidissement [25] de la membrane active [12] à l'aide de joints d'étanchéité [20, 21] intercalés entre les plaques de cellule de collecteur [18, 19]. Le procédé d'exploitation du dispositif de pile à combustible supportant le gel selon l'invention comprend la circulation à travers le circuit de refroidissement [25] d'un fluide réfrigérant autre que l'eau pure, ayant un point de gel suffisamment bas. L'invention concerne également un procédé de démarrage et d'arrêt du dispositif de pile à combustible supportant le gel.
