Abstract

Interconnecteur pour réacteur d’électrolyse ou de co-électrolyse de l’eau (SOEC) ou pile à combustible (SOEFC), Procédé de fabrication associé. L’invention concerne un dispositif formant un interconnecteur électrique et fluidique pour l’électrolyse ou la co-électrolyse à haute température de la vapeur d’eau ou pour une pile à combustible (SOFC). Selon l’invention, le dispositif consiste en une seule pièce monobloc en alliage métallique, allongée selon deux axes de symétrie (X, Y) orthogonaux entre eux, percé de lumières avec des passages assurant les communications fluidiques entre certaines lumières, réalisés par des zones poreuses et/ou des languettes formant des peignes à l’intérieur du cadre. L’invention concerne également le procédé de fabrication d’un tel interconnecteur selon lequel la pièce est réalisée en une seule étape par fabrication additive. Figure pour l’abrégé : Fig. 5Interconnector for water electrolysis or co-electrolysis reactor (SOEC) or fuel cell (SOEFC), associated manufacturing process. The invention relates to a device forming an electrical and fluidic interconnector for the high temperature electrolysis or co-electrolysis of steam or for a fuel cell (SOFC). According to the invention, the device consists of a single one-piece piece of metal alloy, elongated along two axes of symmetry (X, Y) orthogonal to each other, pierced with slots with passages providing fluid communications between certain slots, made by zones porous and/or tabs forming combs inside the frame. The invention also relates to the method of manufacturing such an interconnector according to which the part is produced in a single step by additive manufacturing. Figure for abstract: Fig. 5
