- RADICAL SCAVENGER METHOD FOR PREPARING THE SAME MEMBRANE-ELECTRODE ASSEMBLY COMPRISING THE SAME AND FUEL CELL COMPRISING THE SAME

摘要

The present invention relates to a radical decomposition catalyst, a method for preparing the same, a membrane-electrode assembly including the same, and a fuel cell including the same, wherein the membrane-electrode assembly includes an ion exchange membrane, a catalyst electrode disposed on both surfaces of the ion exchange membrane, respectively; And a radical decomposition catalyst is included in any one position selected from the group consisting of the catalyst electrode, the ion exchange membrane, between the ion exchange membrane and the catalyst electrode, and combinations thereof. The membrane-electrode assembly can improve the chemical durability of the ion exchange membrane and minimize the loss of ion conductivity of the ion exchange membrane itself, prevent chemical deterioration of the ion exchange membrane that occurs during long-term operation of the fuel cell, and provide excellent long-term performance It can be secured and can be used universally regardless of the type of ion exchange membrane such as fluorine-based or hydrocarbon-based.
