Abstract

A continuous process for applying subgaskets to surfaces of CCM subassemblies, comprising:

a) preparation of a roll (A), wherein on each of two surfaces, electrocatalytic layers longitudinally distributed at regular intervals are applied;b) preparation of two subgasket rolls (B) wherein, on a subgasket sheet, in correspondence to the position of the electrocatalytic layers in the roll (A), openings are made; the percent ratio (subgasket opening area)/(electrocatalytic layer area) being between 90% and 99%;c) hot lamination of two rolls (B) with the roll (A); the step being carried out so that the perimeter of the openings of the two rolls (B) falls inside the area of the electrocatalytic layers, and obtaining a roll (C), wherein on each of the two surfaces of the sheet formed of a CCM sequence (roll (A)) a subgasket sheet (roll (B)) is applied.
