▎ 摘　　要

NOVELTY - The bilayer complex proton exchange membrane (100) comprises a first complex structure (102), and a second complex structure (104) laminated to the first complex structure. The first complex structure comprises 0.001-5 wt.% of a graphene derivative with a two-dimensional structure, and 99.999-90 wt.% of a first organic material that includes a first polymer material with a sulfonic acid group and a phosphate group. The second complex structure comprises 0.5-30 wt.% of an inorganic material. A surface area of the inorganic material is 50-3000 m2/g. USE - The bilayer complex proton exchange membrane is useful in an electrode assembly (claimed) that is useful in a micro fuel cell. ADVANTAGE - The thin, bilayer complex proton exchange membrane has high water-retention capacity, less water swelling ratio, enhanced stability, and increased proton conductivity, and increases performance of the electrode assembly so that fuel consumption rate of the fuel cell is decreased and energy efficiency of the fuel cell is increased. DETAILED DESCRIPTION - The bilayer complex proton exchange membrane (100) comprises a first complex structure (102), and a second complex structure (104) laminated to the first complex structure. The first complex structure comprises 0.001-5 wt.% of a graphene derivative with a two-dimensional structure, and 99.999-90 wt.% of a first organic material that includes a first polymer material with a sulfonic acid group and a phosphate group.
