A fuel cell system is operated with the fuel supply pressure greater than the oxidant supply pressure to the fuel cell. This gives improved performance particularly when the fuel cell system is closed an the fuel side. The magnitude of fuel overpressure may be varied in accordance with variations in the fuel cell operating parameters.
L'invention concerne un système de pile à combustible mis en oeuvre au moyen d'une pression d'alimentation du combustible supérieure à celle de l'oxydant dans la pile à combustible. Des performances améliorées peuvent ainsi être obtenues, notamment quand le système de pile à combustible est fermé sur le côté combustible. L'amplitude de la surpression du combustible peut être modifiée en fonction des variations des paramètres de fonctionnement de la pile à combustible.
