(DE) Verbinden von elektrochemischen Zellenbauteilen
(EN) Bonding electrochemical cell components
(FR) Liaison de composants de cellules électrochimiques
Abstract
(EN)
An electrochemical cell subassembly (55) for use within a fuel cell for the generation of electricity. The electrochemical cells subassembly (55) comprises at least one component in the form of a cell frame (58, 64) with the or each cell frame (58, 64) being adhesively bonded to an adjacent component. The bonding can be accomplished using either polymeric bonds (i.e. adhesives) where polymer and/or metal components are involved are mettalurgical bonds (i.e. solder) where metal components are involved. The bonding of the electrochemical cell subassembly (55) provides a tightly sealed cell subassembly, with a low electrical resistance between components of the cell subassembly.

(FR)
L'invention concerne un procédé de préparation de sous-ensembles destinés à une cellule électrochimique ou à une pile de cellules électrochimiques, notamment une pile de piles à combustible permettant la génération directe d'électricité. Le procédé consiste à assembler au moins deux composants de cellules électrochimiques, tels que des plaques, des cadres, des champs de courant, des cales, des joints d'étanchéité, des membranes et autres, pour former des sous-ensembles utilisés dans la formation d'une pile de cellules électrochimiques. L'assemblage peut être réalisé au moyen de liaisons polymères (c'est-à-dire d'adhésifs) impliquant des composants polymères et/ou métalliques ou de liaisons métallurgiques (c'est-à-dire de soudure) impliquant des composants métalliques. L'assemblage produit des cellules hermétiques et des résistances de contact électroniques plus faibles entre les composants.
