摘要： A catalyst complex for fuel cells and a method for manufacturing an electrode including the same are disclosed. The catalyst complex for fuel cells, which is included in an electrode for fuel cells, includes a first catalyst configured to cause hydrogen oxidation reaction (HOR) and a second catalyst configured to cause water electrolysis reaction, i.e., oxygen evolution reaction (OER). The outer surface of the first catalyst is coated with a first ionomer binder, the outer surface of the second catalyst is coated with a second ionomer binder, and an equivalent weight (EW) of the second ionomer binder differs from an equivalent weight (EW) of the first ionomer binder.

摘要： 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.
