Abstract

Un certain nombre de facteurs entraînent la survenue de réactions indésirables qui accélèrent l'usure et la dégradation subie par des composants de pile à combustible pendant les opérations d'arrêt et les périodes de redémarrage. Afin d'atténuer les problèmes associés à ces facteurs, l'invention concerne un module de pile à combustible amélioré comprenant (i) un empilement de piles à combustible comprenant au moins une pile à combustible, chaque pile comprenant une électrode anode, une électrode cathode et un milieu électrolyte agencé entre l'anode et la cathode, en fonctionnement normal, l'électrode anode étant pourvue d'un premier réactif et l'électrode cathode étant pourvue d'un premier mélange contenant un second réactif et un agent non réactif, (11) une charge parasite qui peut être connectée à travers les électrodes anode et cathode, (111) un premier orifice d'alimentation de réactif qui peut être connecté à l'électrode anode destiné à alimenter le premier réactif à l'électrode anode, (iv) un flux latéral qui peut être fluidiquement connecté à la première alimentation de réactif et à l'électrode anode, (v) un réservoir de réactif, qui peut être fluidiquement connecté au flux latéral de façon à stocker une quantité du premier réactif souhaitable pour un processus d'arrêt du module de pile à combustible, en utilisation, lorsque le module de pile à combustible est arrêté, la quantité stockée du premier réactif est amenée du réservoir de réactif et elle réagit électrochimiquement avec le second réactif dans le module de pile à combustible de façon à consommer électrochimiquement le premier et le second réactif, laissant ainsi un second mélange qui comprend sensiblement l'agent non réactif, (vi) et un dispositif de génération de pression, qui peut être connecté fluidiquement au flux latéral et placé en amont du réservoir de réactif pour pressuriser et délivrer le premier réactif en provenance de la première alimentation de réactif au réservoir de réactif.
