A separator suction device for a fuel cell, having a suction plate and a suction pump. A fuel cell separator is placed on the suction plate. The fuel cell separator has flow paths formed as grooves and ridges on one side of thereof and also has a gasket that is a seal member placed around the flow paths. The suction plate attracts the fuel cell separator by suction. The suction pump sucks the fuel cell separator through suction openings formed in the suction plate. The suction plate has a suction groove which receives the gasket and which has a suction opening formed in it. Further, the suction plate preferably has the suction openings at positions where the ridges of the fuel cell separator are to be placed and is made of an elastic material.

La présente invention concerne un dispositif d'aspiration de séparateur pour une pile à combustible ayant une plaque d'aspiration et une pompe d'aspiration. La plaque d'aspiration est équipée d'un séparateur de pile à combustible ayant des voies de passage formées en tant que rainures et saillies d'un côté de la plaque et ayant également un joint statique qui est un élément d'étanchéité placé autour des voies de passage, et la plaque d'aspiration adsorbe le séparateur de pile à combustible. La pompe d'aspiration aspire le séparateur de pile à combustible à partir d'ouvertures d'aspiration formées dans la plaque d'aspiration. La plaque d'aspiration a une rainure d'aspiration permettant de recevoir le joint statique et ayant une ouverture d'aspiration formée dans celle-ci. En outre, les ouvertures d'aspiration de la plaque d'aspiration sont de préférence disposées à des positions où les saillies du séparateur de pile à combustible sont placées et la plaque d'aspiration est constituée d'un matériau élastique.
