Abstract
(EN)
The present invention provides a redox flow cell such that crossover of a redox mediator can be suppressed and a high capacity can thereby be maintained for long periods of time. The redox flow cell according to an embodiment of the present invention comprises: a first nonaqueous liquid (110) that includes a first electrode mediator (111); a first electrode (210) that has at least a portion that is in contact with the first nonaqueous liquid (110); a second nonaqueous liquid (120); a second electrode (220) that is a counter electrode of the first electrode (210) and has at least a portion that is in contact with the second nonaqueous liquid (120); and a separating part (400) that has pores and separates the first nonaqueous liquid (110) from the second nonaqueous liquid (120). The inner surface of the pores is modified by a functional group including a hydrocarbon group.

La présente invention concerne une cellule à flux redox de telle sorte que le croisement d'un médiateur redox peut être supprimé et qu'une capacité élevée peut ainsi être maintenue pendant de longues périodes. La cellule à flux redox selon un mode de réalisation de la présente invention comprend : un premier liquide non aqueux (110) qui comprend un premier médiateur d'électrode (111); une première électrode (210) qui a au moins une partie qui est en contact avec le premier liquide non aqueux (110); un second liquide non aqueux (120); une seconde électrode (220) qui est une contre-électrode de la première électrode (210) et a au moins une partie qui est en contact avec le second liquide non aqueux (120); et une partie de séparation (400) qui a des pores et sépare le premier liquide non aqueux (110) du second liquide non aqueux (120). La surface interne des pores est modifiée par un groupe fonctionnel comprenant un groupe hydrocarboné.
