CATALYST COMPLEX FOR FUEL CELLS AND A METHOD FOR MANUFACTURING AN ELECTRODE INCLUDING THE SAME

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.
