摘要： The present invention provides a method of fabricating a membrane-electrode assembly for a polymer electrolyte membrane fuel cell, and a membrane-electrode assembly and a polymer electrolyte membrane fuel cell formed thereby. In the method, a 3-layered membrane-electrode assembly is formed in which a catalyst electrode layer is disposed on both surfaces of a polymer electrolyte membrane. A sub-gasket having an opening therein and having a primer layer formed on one surface thereof is formed, and is attached on both surfaces of the 3-layered membrane-electrode assembly such that the surface of the sub-gasket having the primer layer formed thereon faces the outside (is exposed) and the catalyst electrode layer is exposed through the opening. A 7-layered membrane-electrode assembly is then formed by stacking a gas diffusion layer on the primer layer exposed on both surfaces of the 5-layered membrane-electrode assembly to cover the catalyst electrode layer, and then performing a hot-pressing process to attach the sub-gasket and the gas diffusion layer to each other via the primer layer.
