(EN) METHOD OF MANUFACTURING SEPARATOR FOR FUEL CELL
(FR) PROCEDE DE FABRICATION DE SEPARATIONS POUR PILE A COMBUSTIBLE
Abrégé
(EN)
A method of manufacturing a separator for fuel cell, comprising the steps of forming separators (41, 95, 107) with cores by providing cores (31, 94) between two preforms (17, 90, 101), and heating the separators to fuse and discharge the cores so as to form a plurality of cooling water passages (54), whereby the need of sealing can be eliminated since the separators must not be stuck on each other to form the cooling water passages, and since the separators must not be stuck on each other, an electric contact resistance is also lowered.
(FR)
Cette invention concerne un procédé de fabrication de séparations pour pile à combustible. Ce procédé consiste à former des séparations (41, 95, 107) au moyen de noyaux (31, 94) disposés entre deux préformes (17, 90, 101) et à chauffer ces séparations de manière à faire fondre et à éliminer les noyaux. On obtient ainsi une pluralité de passages d'eau (54) qui rendent superflu l'emploi d'un système d'étanchéité du fait que les séparations n'ont pas besoins d'être collées les unes sur les autres pour former les passages d'eau, ce qui procure par ailleurs une baisse de la résistance électrique par contact.
