Abstract:

(EN)A method of restoring the proton conductivity of a sintered pyrophosphate membrane of intermediate temperature fuel cells (IT-FCs) by introducing phosphoric acid into the sintered SnP₂O₇ membrane to react with the degraded SnP₂O₇ species and thus restore the membrane pyrophosphate and proton conductivity. Such cells operate with low external humidification, and the active area of the cells may be fabricated up to 100 cm² in size.
(FR)L'invention concerne une méthode de restauration de la conductivité protonique d'une membrane de pyrophosphate frittée d'une pile à combustible à température intermédiaire (IT-FCs) par l'introduction d'acide phosphorique dans la membrane frittée SnP₂O₇ pour réagir avec les espèces dégradées SnP₂O₇ et ainsi restaurer la membrane de pyrophosphate et la conductivité protonique. De telles piles fonctionnent avec une faible humidification externe, et la zone active des piles peut être fabriquée jusqu'à 100 cm ² en taille.
