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.

Abstract: A system for activating a fuel cell includes a flow meter for measuring the amount of water discharged from an outlet of the air electrode and an outlet of the fuel electrode; a pressure sensor for measuring the pressure at the respective outlets; and a back pressure regulator receiving flow values measured by the flow meters and pressure values measured by the pressure sensors, which are fed back from a controller, and regulating a pressure difference (ΔP=PCathode−PAnode) to be a value greater than 0. With the system, the activation time of a fuel cell and the amount of hydrogen used for the activation can be reduced, thus improving the productivity and manufacturing cost.
