MEMBRANE ECHANGEUSE DE CATIONS, SON PROCEDE DE FABRICATION ET SON APPLICATION EN TANT QU'ELECTROLYTE SOLIDE

摘要

Cation exchanger diaphragm which can in particular be used as a solid electrolyte. This diaphragm comprises a grafted copolymer film, particularly polyethylene grafted by styrene and has an exchange capacity exceeding 0.5 meq/g, a resistivity below 100 OMEGA .cm, a swelling in water exceeding 30% compared with the dry mass and a permeability relative to oxygen and hydrogen such that in the electrolysis of water these two gases are obtained with a purity level exceeding 98%.
