Abstract

Un système de pile à combustible peut être équipé d'un système de rampe de distribution à plusieurs orifices de façon à apporter différents fluides de façon plus efficace quant à la pression, et de façon à permettre une plus grande adaptabilité de l'encombrement au sol de la pile à combustible. Ces différents orifices peuvent être prévus pour l'entrée de réactants, la sortie de réactants, et les produits de réaction, l'entrée et la sortie des réfrigérants, ou des combinaisons de ces courants de fluides. Un réactant entre dans une zone active (16) par plusieurs orifices d'entrée (12) via un ensemble de canaux de liaison (14) puis ressort de la zone active vers plusieurs orifices de sortie (18) via un autre ensemble de canaux de liaison (20). L'arrivée des gaz au niveau de ces orifices peut se faire par une rampe de distribution au niveau du capot de tête de l'empilement d'éléments de pile à combustible, ou sur la longueur de la pile à combustible.
