Title
(EN) PURGED ANODE, LOW EFFLUENT FUEL CELL
(FR) ANODE PURGEE, PILE A FAIBLE COMBUSTIBLE EFFLUENT
Abstract
(EN)
A hydrogen-fueled fuel cell reacts residual fuel in the exhaust of the anode flow field (16') either in a catalytic converter (69) or by feeding the anode exhaust (50) into the cathode oxidant stream (74). Control of flow of anode exhaust (50) into the cathode oxidant stream (74) may be in response to a flammability sensor (54), a gas composition analyzer (57), current output, or periodically in response to a timer (66); the anode exhaust (50) may be fed either upstream or downstream of the cathode air inlet blower (30).
(FR)
L'invention concerne une pile à combustible à hydrogène qui fait réagir le combustible résiduel dans l'échappement du champ d'écoulement de l'anode (16') soit dans un convertisseur catalytique (69), soit par l'introduction de l'échappement de l'anode (50) dans le flux (74) d'oxydation de la cathode. La commande du débit de l'échappement de l'anode (50) dans le flux (74) d'oxydation de la cathode peut intervenir en réponse à un détecteur d'inflammabilité (54), d'un analyseur de composition gazeuse (57), d'un courant de sortie ou, périodiquement, en réponse à une horloge (66). L'échappement de l'anode (50) peut être introduit soit en amont, soit en aval de la soufflante d'admission d'air de la cathode (30).
