La présente invention concerne un appareil à cellule électrolytique avec présentant des chambres d'anode et de cathode séparées pour la préparation électrolytique d'eau ozonée, ledit appareil comprenant une cuve électrolytique, la cuve électrolytique étant pourvue d'une électrode cathodique (5) et d'une électrode anodique (3), le fond de l'électrode cathodique (5) et de l'électrode anodique (3) étant en contact avec le fond de la cuve électrolytique, la cuve électrolytique étant séparée en une chambre d'anode (6) et une chambre de cathode (7) indépendantes l'une de l'autre, une partie de séparation de la chambre d'anode (6) et de la chambre de cathode (7) étant agencée de manière à permettre à un ion de traverser tout en empêchent l'hydrogène de traverser un film d'échange de protons (8) d'une région d'anode. Dans le concept structural décrit ci-dessus, la chambre d'anode (6) et la chambre de cathode (7) sont séparées et ne sont pas en communication l'une avec l'autre, de sorte que l'eau dans la chambre de cathode (7) ne peut pas se mélanger dans la chambre d'anode (6), et, par conséquent, on empêche que l'hydrogène généré dans la chambre de cathode (7) ne se mélange dans la chambre d'anode (6) pour amener une réaction de neutralisation avec l'ozone O3, ce qui permet de réduire la consommation d'ozone O3 et d'améliorer l'efficacité de production et la teneur en ozone O3.
