Abstract

L'invention porte sur un générateur d'eau électrolytique (1), qui comporte des éléments de support (24e) qui supportent les deux extrémités d'une membrane barrière (23) dans la direction d'écoulement dans un canal d'eau, et qui constituent également des surfaces de canaux d'eau (25, 26), et de multiples parties de régulation (24f) qui sont disposées aux deux extrémités au niveau des éléments de support (24e) dans la direction d'écoulement de canaux d'eau (25, 26) et qui régulent la distance entre la membrane barrière (23) et des plaques d'électrode (21, 22). Une épaisseur (t1), dans la direction d'épaisseur de la membrane barrière (23), dans une partie (24m) de l'élément de support (24e) qui est reliée à la membrane barrière (23) à l'extrémité aval dans la direction d'écoulement de canaux d'eau (25, 26), et qui constitue une surface des canaux d'eau, n'est pas supérieure à une épaisseur (t2) de la membrane barrière (23).
