Abstract
Described herein is a composition for manufacturing an electrode of a membrane-electrode assembly for fuel cells and a method for manufacturing an electrode of a membrane-electrode assembly for fuel cells including the same. More particularly, described herein is a composition for manufacturing an electrode of a membrane-electrode assembly for fuel cells which can improve porosity in the electrode and thereby mass transport capability of reactive gases by mixing a second carbon having lower crystallinity than a first carbon to produce an electrode and applying a voltage to the electrode to remove only the second carbon, and a method for manufacturing an electrode of a membrane-electrode assembly for fuel cells including the same.
