Abstract

Prezenta inventie se refera la o noua celula pentru electroliza solutiilor de halogenuri, prevazuta cu anod si catod separati printr-o membrana sau o diafragma permeabila, în care electrozii porosi sunt presati în contact direct cu una sau cu ambeleparti ale membranei sau diafragmei prin intermediul unui strat electric compresibil. Tesatura din care este facut stratul elastic este substantial coextensiva cu extinderea electrodului opus si/sau cu zona activa, electronica a diafragmei sau membran ei si este astfel construita ca atunci cînd este comprimata sa exercite presiune reactiva elastica uniforma pe membrana pe o portiune majora sau pe întreaga zona opusa contra electrodului.
