Abstract
Membrane semi-perméable, constituée par une feuille ou un film d'une résine synthétique dans laquelle on a créé une multitude de picopores, et qui présente la propriété de laisser passer les ions hydrogène et oxygène exclusivement par électroosmose, sans laisser passer les autres ions, et son procédé de préparation. Cette membrane est utilisable comme séparateur des compartiments anodiques et cathodiques et comme film d'enrobage d'une électrode dans les piles et accumulateurs à double électrolyte.
