Abstract
(EN)
This redox flow cell comprises: a first non-aqueous fluid (110) including a first non-aqueous solvent, a first electrode mediator (111), and metal ions; a first electrode (210); a second non-aqueous fluid (120) including a second non-aqueous solvent; a second electrode (220) being a counter electrode for the first electrode (210); and an isolating section (400) that has a plurality of holes and separates the first non-aqueous fluid (110) and the second non-aqueous fluid (120) from each other. The average hole diameter of the plurality of holes is greater than the size of the metal ions and is less than the size of the first electrode mediator (111) solvated by the first non-aqueous solvent.

La présente invention concerne une cellule à flux redox comprenant : un premier fluide non aqueux (110) comprenant un premier solvant non aqueux, un premier médiateur d'électrode (111) et des ions métalliques ; une première électrode (210) ; un second fluide non aqueux (120) comprenant un second solvant non aqueux ; une seconde électrode (220) qui est une contre-électrode pour la première électrode (210) ; et une section isolante (400) qui possède une pluralité de trous et qui sépare le premier fluide non aqueux (110) et le second fluide non aqueux (120) l'un de l'autre. Le diamètre de trou moyen de la pluralité de trous est supérieur à la taille des ions métalliques et est inférieur à la taille du premier médiateur d'électrode (111) solvaté par le premier solvant non aqueux.
