Platinum ruthenium carbon catalyst is a noble metal catalyst primarily used in the fuel cell​ field, particularly as an anode catalyst for proton exchange membrane fuel cells (PEMFC). It effectively catalyzes the oxidation reaction of hydrogen, improving the power generation efficiency and stability of fuel cells. Additionally, this catalyst has significant applications in electrochemical hydrogen evolution reaction (HER), electrochemical oxygen evolution reaction (OER), and organic synthesis reactions, demonstrating high catalytic activity and strong resistance to poisoning.
