Title
(EN) A SEPARATOR FOR WATER ELECTROLYSIS
(FR) SÉPARATEUR POUR ÉLECTROLYSE DE L'EAU
Abstract
(EN) A separator for alkaline electrolysis comprising a support (10) and a porous layer (20) provided on the support, characterized in that the support is capable of being substantially removed from the separator. The support is preferably removed by the electrolyte of an alkaline electrolyser.
(FR) Un séparateur pour électrolyse alcaline comprend un support (10) et une couche poreuse (20) disposée sur le support, le support étant caractérisé en ce qu'il est apte à être sensiblement retiré du séparateur. Le support est de préférence retiré par l'électrolyte d'un électrolyseur alcalin.
