      摘要： A continuous process for applying subgaskets to both the flat surfaces of CCM assemblies, comprising the following steps:
      a) preparation of a roll (A) formed of a composite (20) consisting in one central layer (1), formed of an ionomeric membrane sheet, wherein on each of the two surfaces, electrocatalytic layers (2) longitudinally distributed at regular intervals are applied, said layers being on each of the two surfaces in symmetric position among each other with respect to the membrane plane;
      b) preparation of two subgasket rolls (B) wherein, on a subgasket sheet (21), in correspondence to the position of the electrocatalytic layers (2) in the roll (A), openings (3) are made; the per cent ratio (subgasket opening area (3))/(electrocatalytic layer area (2)) being between 90% and 99%;
      c) hot lamination of two rolls (B) with the roll (A), carried out by feeding the roll (A) between the two rolls (B), with the two drums (8) for the lamination; the step being carried out so that the perimeter of the openings (3) of the two rolls (B) falls inside the area of the electrocatalytic layers (2), and obtaining of a roll (C), wherein on each of the two surfaces of the sheet formed of a CCM sequence (roll (A)) a subgasket sheet (5) (roll (B)) is applied.
