Title
(EN) INTERCONNECT WITH MICROCHANNELS AND METHOD OF MAKING
(FR) INTERCONNEXION À MICROCANAUX ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract
(EN)
The present invention is an interconnect for an electrochemical reactor that includes at least one microchannel. The at least one microchannel has a cross-sectional area orthogonal to a flow path and where the cross-sectional area is no greater than 1 mm2. Preferably, the microchannel has a planar projection area PPAc and the interconnect has a planar projection area PPAi, wherein the ratio of PPAc/PPAi is in the range of 0.2 - 0.8, or 0.3 - 0.7, or 0.4 - 0.6, or 0.45 - 0.55.
(FR)
La présente invention concerne une interconnexion pour un réacteur électrochimique qui comprend au moins un microcanal. Le ou les microcanaux ont une surface de section transversale orthogonale à un trajet d'écoulement, la surface de section transversale n'étant pas supérieure à 1 mm2. De préférence, le microcanal comporte une surface de projection plane PPAc et l'interconnexion présente une surface de projection plane PPAi, le rapport de PPAc/PPAi se situant dans la plage de 0,2 à 0,8, ou de 0,3 à 0,7, ou de 0,4 à 0,6, ou de 0,45 à 0,55.
