PT-AU ALLOY CATALYST HAVING RESISTANCE TO PHOSPHORIC ACID POISONING, MEA AND HIGH TEMPERATURE PEMFC INCLUDING THE SAME AND METHOD FOR PREPARING THE SAME

摘要

In the present invention, provided are an alloy catalyst of platinum and gold having resistance to poisoned phosphate, a membrane-electrode assembly, polymer fuel cell at high temperatures including the same and a manufacturing method thereof wherein the alloy catalyst of platinum and gold has strong resistance to poisoned phosphate while having a high activity for oxygen and reduction reaction (ORR), thereby being used in polymer electrolyte membrane fuel cells at high temperatures having a poisoned phosphate caused by using phosphate impregnation membrane.
