Abstract

L'invention concerne un séparateur (16) de pile qui ne comprend pas de couche de matière membraneuse. Le séparateur (16) comprend deux couches (16a, 16b) de matières disposées de façon adjacente l'une par rapport à l'autre. Les couches peuvent être constituées de la même matière ou de matières différentes. Les matières peuvent être tissées ou non tissées. Dans certains modes de réalisation, les couches sont constituées de la même matière non tissée et non membraneuse, qui est une matrice de fibres de polyalcool vinylique, de fibres de cellulose et d'un liant de polyalcool vinylique.
