Title:
METHOD FOR MANUFACTURING MEMBRANE-ELECTRODE ASSEMBLY WITH SUB-GASKET, DEVICE FOR MANUFACTURING MEMBRANE-ELECTRODE ASSEMBLY WITH SUB-GASKET, AND SUB-GASKET SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2021/010047
Kind Code:
A1
Abstract:
A sub-gasket substrate (9) includes, in order, an elongated strip-shaped second back sheet (91), a sub-gasket film (92), and a cover film (93). A second half-cut unit (4) provides a cut portion (9C) that reaches from the surface of the cover film (93) up to a thickness direction intermediate part of the second back sheet (91), along a corresponding region (9A1) which corresponds to a first catalyst layer (83) of an electrode layer substrate (8) . A cover film collection roller (23) peels off and collects a non-corresponding region (9A2) of the cover film (93) from the sub-gasket substrate (9). An affixing mechanism (5) positions the first catalyst layer (83) and the corresponding region (9A1) of the cover film (93), and affixes the electrode layer substrate (8) and the sub-gasket substrate (9) to each other.
