Platinum on Carbon (Pt/C) is the industry-standard catalyst for handling the hydrogen-side reactions in both fuel cells and electrolyzers. The role of the Pt/C electrode changes dramatically depending on whether it is "pushing" electrons (electrolysis) or "pulling" them (fuel cell).
In an PEM electrolyzer, (1) Hydrogen Evolution (HER): Pt/Vulcan is the standard cathode for water splitting. (2) Cathode Environment: Since the cathode operates at low (reducing) potentials, the Vulcan XC-72 carbon is extremely stable and can last for tens of thousands of hours without degrading
In PEM fuel cell, (1) Oxygen Reduction (ORR): Most commercial cathode catalysts are 20% to 60% Pt/Vulcan. The carbon must provide a stable path for electrons to reach the oxygen molecules. (2) Durability: At the cathode, the high voltage and moisture can cause the Vulcan XC-72 to slowly corrode (carbon oxidation). Researchers often use "Graphitized" Vulcan (heat-treated at >1000°C) to make the carbon more resistant to this decay.
