    • The present invention relates to a polymer electrolyte membrane-electrode assembly with an enhanced hydrophobicity by maximizing the surface area by forming a nanopattern with a high aspect ratio on the catalytic carrier on the surface of a catalyst layer in order to supply ultra hydrophobicity to the surface of the catalyst layer, and by coating a hydrophobic thin film on the surface, and a manufacturing method thereof. The present invention provides a manufacturing method of a polymer electrolyte membrane-electrode assembly, which comprises a step of forming a nanopattern with a high aspect ratio by plasma-etching the catalyst carrier on the surface of a catalyst layer forming MEA; and a step of forming a hydrophobic thin film on the nanopattern formed on the catalyst carrier.
