Patent

CA 2222032

A fuel gas and an oxygen containing gas are supplied downwardly through different passages into a first manifold plate 42, a first surface pressure generating plate 44, a separator body 48, a second surface pressure generating plate 46, a second manifold plate 50, a first gasket 30, a solid polymer electrolyte membrane 22, and a second gasket 32, into which cooling water is supplied upwardly. The cooling water rises upwardly in the separator body 48 to reduce a temperature distribution in a fuel cell 20.

Du gaz combustible et du gaz comburant sont acheminés par différents passages au-dessus d'une première plaque de collecteur (42), d'une première plaque (44) plane de génération de pression, d'un élément séparateur (48), d'une seconde plaque plane de génération de pression, d'une seconde plaque de collecteur (50), d'un premier joint d'étanchéité (30), d'une pellicule (22) constituée par un électrolyte à polymère solide et d'un second joint d'étanchéité (32), de l'eau de refroidissement étant amenée par en-dessous. Cette dernière coule vers le haut dans l'élément séparateur (48), ce qui uniformise la répartition de la température d'une pile à combustible (20).
