Abstract

L'invention concerne des dispositifs et des procédés pour diaphragmes d'électrodes dans lesquels un diaphragme polymère hydrophobe est prétraité avec des ions présents dans un électrolyte dans des conditions qui sont efficaces pour augmenter la mouillabilité du diaphragme. Il est envisagé que le diaphragme puisse d'abord être exposé à un agent mouillant puis placé dans un électrolyte aqueux utilisé dans un procédé électrochimique. Le courant peut être appliqué en une quantité suffisante pour entraîner des ions de la solution ionique dans le diaphragme polymère.
