Abstract
A membrane-electrode assembly, a method for manufacturing the membrane-electrode assembly, and a fuel cell including the membrane-electrode assembly are disclosed. The membrane-electrode assembly includes: an ion exchange membrane; catalyst layers disposed on both sides of the ion exchange membrane respectively; and a functional modification layer disposed between the ion exchange membrane and each of the catalyst layers. The membrane-electrode assembly has a low hydrogen permeability without a reduction of hydrogen ion conductivity, has excellent interfacial bonding properties between the catalyst layers and the ion exchange membrane, and has excellent performance and durability under high temperature/low humidity conditions.
