Bilayer complex proton exchange membrane and membrane electrode assembly

A bilayer complex proton exchange membrane, included in a membrane electrode assembly, consists of:

• a first complex structure near an anode of the membrane electrode assembly, comprising:
• 0.001 wt % to 0.2 wt % of graphene oxide;
• and 99.999 wt % to 90 wt % of a first organic material that includes a PTFE-PFSA copolymer;
• and
• a second complex structure laminated to the first complex structure, and the second complex structure is near a cathode of the membrane electrode assembly, wherein the second complex structure comprises:
• 0.5 wt % to 30 wt % of an inorganic material, wherein a surface area of the inorganic material is 50 m2/g to 3000 m2/g;
• and
• 99.5 wt % to 70 wt % of a second organic material that includes a second polymer material with the sulfonic acid group or the phosphate group.
