Pohang University of Science & Technology engineers enhance hydrogen fuel cell durability via tungsten oxide coating that functions as a shield. The research has received recognition and was featured on the front cover of the international journal Science Advances. Fuel cells used in hydrogen vehicles has shown that when they are initiated or brought to a sudden halt (start-up/shut-down, SU/SD), external air is drawn into the vehicle. The oxygen present in this air triggers an unintended electrochemical reaction within the fuel cell,…
