Abstract
Graphitic-carbon nitride materials (gCNM) are investigated for developing highly-durable catalyst supports for polymer electrolyte fuel cells (PEFCs). The gCNMs are more electrochemically stable compared to conventional carbon black (Vulcan XC-72) following accelerated corrosion testing. After 2000 scans, the gCNM shows a 133% increase in double-layer capacitance compared to 166% for Vulcan. Despite the low initial electrochemical surface area (ECSA), Pt/gCNM electrocatalyst exhibits improved durability over Pt/Vulcan, with 20.9% ECSA loss versus 41.0% for Pt/Vulcan after 1000 scans. Superior methanol oxidation activity is observed for Pt/gCNM on the basis of the catalyst ECSA. © The Electrochemical Society.
