Abstract
Disclosed is a membrane electrode assembly with enhanced hydrophobicity and a method for manufacturing the same. In particular, a nano pattern with a high aspect ratio is formed in a catalyst support on the surface of a catalyst layer constituting the membrane electrode assembly using plasma etching. A hydrophobic thin film is then formed on the nano pattern formed in the catalyst support.
