Abstract

L'invention concerne une cellule d'électrolyse, comprenant deux éléments (2, 3) comprenant chacun une partie centrale (4, 5) délimitant une chambre anodique (6) et une chambre cathodique (7), respectivement, et une partie d'épaulement circonférentielle (8, 9), un séparateur en forme de feuille (12) doté d'un bord circonférentiel (13), le séparateur (12) étant disposé entre les deux éléments (2, 3) et séparant les chambres anodique et cathodique (6, 7), et un agencement d'étanchéité (14) comprenant au moins un premier (15) et un second joint d'étanchéité (16), l'agencement d'étanchéité (14) étant disposé dans un espace (17) entre les parties d'épaulement (8, 9), le premier joint d'étanchéité (15) étant un joint interne positionné dans une partie de l'espace (17) adjacente aux chambres (6, 7) et le second joint d'étanchéité (16) étant un joint d'étanchéité externe positionné dans une partie de l'espace (17) à distance des chambres (6, 7), les joints d'étanchéité (15, 16) étant à distance l'un de l'autre dans l'espace (17) à un intervalle (I) et le bord circonférentiel (13) du séparateur (12) étant situé radialement entre un point milieu (M1) du premier joint d'étanchéité (15) et un point milieu (M2) du second joint d'étanchéité (16).
