Abstract

Cette invention concerne un dispositif de génération d'eau électrolysée comprenant : une chambre d'électrolyse 30 et une chambre d'électrolyse 40 ; un premier dispositif d'alimentation en énergie 31 et un second dispositif d'alimentation en énergie 32 qui sont agencés dans la chambre d'électrolyse 30 ; un premier dispositif d'alimentation en énergie 41 et un second dispositif d'alimentation en énergie 42 qui sont agencés dans la chambre d'électrolyse 40 ; une membrane de séparation 33 qui sépare la chambre d'électrolyse 30 en une première chambre d'électrode 30a côté premier dispositif d'alimentation en énergie 31 et en une seconde chambre d'électrode 30b côté second dispositif d'alimentation en énergie 32 ; et une membrane de séparation 43 qui sépare la chambre d'électrolyse 40 en une première chambre d'électrode 40a côté premier dispositif d'alimentation en énergie 41 et en une seconde chambre d'électrode 40b côté second dispositif d'alimentation en énergie 42. Une surface du premier dispositif d'alimentation en énergie 31 de la chambre d'électrolyse 30 est formée par un métal adsorbant l'hydrogène. Le dispositif de génération d'eau électrolysée 1 comprend un trajet d'eau intermédiaire 51 qui guide, vers la seconde chambre d'électrode 40b de la chambre d'électrolyse 40, l'eau électrolysée qui a été électrolysée dans la première chambre d'électrode 30a de la chambre d'électrolyse 30.
