A method for manufacturing a sub-gasket-forming membrane electrode assembly, an apparatus for manufacturing a sub-gasket-forming membrane electrode assembly, and a sub-gasket base material

摘要

The sub-gasket base material 9 has the 2nd back sheet|seat 91 of elongate strip|belt shape, the sub-gasket film 92, and the cover film 93 in order. The second half-cut portion 4 is formed along the corresponding region 9A1 corresponding to the first catalyst layer 83 of the electrode layer substrate 8 in the thickness direction of the second back sheet 91 from the surface of the cover film 93 . A cut portion 9C reaching to the middle portion is formed. The cover film collection roller 23 peels and collects the non-corresponding region 9A2 of the cover film 93 from the sub-gasket base material 9 . The sticking mechanism 5 bonds the electrode layer base material 8 and the sub-gasket base material 9 together, aligning the corresponding area|region 9A1 of the 1st catalyst layer 83 and the cover film 93.
