World’s 1st platinum-magnesium fuel cell catalyst unveiled, to boost efficiency | Scientists say the new fuel cell catalyst made from platinum and magnesium delivers exceptional efficiency and durability, potentially transforming clean energy technology.
Scientists unveil the world’s first platinum-magnesium fuel cell catalyst, offering enhanced efficiency, durability, and cost-effectiveness.
This is a significant achievement because, for years, researchers have known that platinum alloys with alkaline Earth metals hold immense potential for fuel cells due to their high catalytic activity and stability. Theoretical studies show that the activity stems from a combination of ligand and strain effects between the intermetallic core and the platinum-rich shell, while the stability originates from magnesium’s high vacancy formation energy in the alloy. “This new development doesn’t just make fuel cells work better; it also paves the way for using platinum-magnesium nanoparticles in other energy technologies, like hydrogen production and other electrochemical reactions,” said Caleb Gyan-Barimah, first author of the study.
