(FR) RÉHYDRATATION DE CELLULES ÉLECTROCHIMIQUES
Abrégé
(EN)
One or more operating parameters, such as electrical current flow from and air flow to, a fuel cell stack within a fuel cell assembly is periodically modulated during rehydration intervals to intermittently increase hydration levels of the fuel cell stack independently of the electrical current demand on the fuel cell assembly from an external load, while maintaining electrical current delivery to that external load.
(FR)
Dans la présente invention, au moins un paramètre de fonctionnement tel que le flux de courant électrique sortant d'un empilement de cellules électrochimiques et le flux d'air envoyé à un tel empilement de cellules électrochimiques, est modulé périodiquement au cours d'intervalles de réhydratation en vue d'augmenter les niveaux d'hydratation de l'empilement de cellules électrochimiques indépendamment de la demande en courant électrique s'appliquant sur l'ensemble de cellules électrochimiques par un charge externe, tout en maintenant la distribution de courant électrique pour cette même charge externe.
