Abstract

L'invention concerne une cellule électrolytique subdivisée en deux compartiments par une membrane échangeuse de cations, le compartiment cathodique contenant une cathode de diffusion d'oxygène en contact avec la membrane par l'intermédiaire d'une couche poreuse hydrophile catalysée et le compartiment anodique comprenant une anode pourvue d'un revêtement catalytique pour le dégagement de chlore, cette anode étant espacée de la membrane. La cellule de l'invention permet de produire du chlore présentant une teneur en oxygène réduite et un produit caustique de concentration appropriée sans qu'il soit nécessaire de diluer l'alimentation en saumure ou d'humidifier le flux d'oxygène.
