NOVELTY - Highly enhanced composite membrane electrode with fluorine-containing proton or ion exchange membrane comprises two layers of microporous reinforced membrane, where both sides of each microporous reinforced membrane are filled with fluorine-containing proton or ion exchange resin, and the weight ratio of the microporous reinforced membrane to the fluorine-containing proton or ion exchange resin is 5:95-40:60. The weight ratio of the microporous enhanced membrane to the fluorine-containing proton or ion exchange resin is 10:90-30:70. The total weight of the composite membrane electrode of the special high-enhanced fluorine-containing proton or ion exchange membrane is 2-500 g/m2, and the thickness is 1 micron to 300 micron. The tensile strength of the composite membrane electrode of the special high-enhanced fluorine-containing proton or ion exchange membrane is greater than 40MPa in both directions. USE - Highly enhanced composite membrane electrode with fluorine-containing proton or ion exchange membrane used in battery separator. ADVANTAGE - The tensile strength of the composite membrane electrode of the special high-reinforced fluorine-containing proton or ion exchange membrane is greater than 40MPa in both directions, its normal temperature ion conductivity is greater than 0.007S/cm, and the air permeability is extremely low. The time required for 100ml of air to pass through the composite membrane electrode measured by Gurley gas meter is greater than 5 minutes.
