Title
(EN) A METHOD OF OPERATING A FUEL CELL
(FR) PROCÉDÉ DE FONCTIONNEMENT D'UNE PILE À COMBUSTIBLE
Abstract
(EN) The present invention relates to a method of determining the net water drag coefficient (rd) in a fuel cell. By measuring the velocity of the fluid stream at the outlet of the anode, rd can be determined. Real time monitoring and adjustments of the water balance of a fuel cell may be therefore achieved.
(FR) La présente invention concerne un procédé de détermination du coefficient net de transport d'eau (rd) dans une pile à combustible. Par mesure de la vitesse du flux de fluide à la sortie de l'anode, rd peut être déterminé. Une surveillance et des ajustements en temps réel de l'équilibre en eau d'une pile à combustible peuvent être ainsi réalisés.
