Punching cut the frame and remove waste material

1.Cutting accuracy ≤± 0.1mm

2.Die accuracy ± 0.05mm

3.Incoming SG material thickness 35-100um 

Cut GDL sheet or roll into specified size

1.Cutting accuracy ≤± 0.1mm

2.Die accuracy ± 0.05mm

3.GDL incoming material thickness 120-280um

Manually repeat the feeding of the frame on the other side, start the machine to finish the second side fitting, and align the cut frame with CCM to form a five layer membrane electrode assembly

1.Yield ≥ 95% (except for incoming material and operation)

2.Fitting accuracy of CCM and frame ≤± 0.3mm

3.Frame and frame fitting accuracy ≤± 0.3mm

GDL dispensing Machine is used to dispense the cut cathode and anode sheet GDL, load and unload materials manually, and trigger dispensing manually. It also has the function of path writing.

1.Width of glue line after dispensing ≤ 2mm 

2.Dispensing position tolerance ≤± 0.2mm

Manually align gluing completed GDL with MEA-5 five layer film electrode semi-finished products through tooling, and then use hot press machine for heating and fixing.

1.Alignment accuracy of GDL and MEA-5 ± 0.3mm

2.Temperature accuracy ± 3 ℃ (working face)

3.Pressure accuracy ± 1% F. S
