Abstract

CELLULE D'ELECTROLYSE 11, 13 AVEC ELECTROLYTE A BASE DE POLYMERE SOLIDE 31 COMPORTANT UNE MEMBRANE PERMIONIQUE 33 A ACIDE CARBOXYLIQUE INTERCALEE ENTRE L'ANOLYTE ET LE CATHOLYTE, ET PROCEDE UTILISANT CETTE CELLULE. LA CATHODE PEUT ETRE UNE CATHODE DEPOLARISEE. ELLE PEUT D'AUTRE PART ETRE UN BORURE. LES ELECTROCATALYSEURS, PAR EXEMPLE L'ANODE ET LA CATHODE, PEUVENT ETRE FIXES A LA MEMBRANE PERMIONIQUE PAR DEPOT CHIMIQUE. L'ANODE PEUT ETRE CONSTITUEE PAR DES PARTICULESAVEC UNE SUBSTANCE HYDROPHOBE. LES PARTICULES INDIVIDUELLES DE L'ANODE PEUVENT ETRE ALLONGEES PAR DU SILICIUM. LE PROCEDE PEUT ETRE MIS EN OEUVRE SOUS HAUTE PRESSION, DE MANIERE A FOURNIR DU CHLORE LIQUIDE QUI EST ENSUITE SEPARE DE LA SAUMURE. APPLICATION A L'ELECTROLYSE DES SAUMURES DE CHLORURE DE METAL ALCALIN.
