- 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 decomposing catalyst, a manufacturing method thereof, a membrane-electrode assembly including the catalyst, and a fuel cell including the same. The membrane-electrode assembly comprises: an ion exchange membrane; catalyst electrodes placed on both surfaces of the ion exchange membrane, respectively; and a radical decomposing catalyst placed at one among a position inside the catalyst electrode, a position inside ion exchange membrane, a position between the ion exchange membrane and the catalyst electrode, and a position selected from a group consisting of combinations thereof. Therefore, the membrane-electrode assembly can improve chemical durability of an ion exchange membrane, minimize loss of ion conductivity of the ion exchange membrane itself, prevent chemical degradation of the ion exchange membrane, which is generated from long-term driving of a fuel cell, secure excellent long-term performance, and can be universally used regardless of the type of ion exchange membrane such as a fluoride base or a hydrocarbon base.
