Research reveals that enhanced Pt durability increases carbon corrosion in PEMFCs, suggesting a need for co-optimization in catalyst design.
Stringent durability demands on oxidation-resistant Pt and corrosion-tolerant carbon in heavy-duty vehicle (HDV) proton exchange membrane fuel cells (PEMFCs) are recognized, yet the catalytic role of anti-oxidative Pt in accelerating carbon corrosion is often overlooked. We investigated carbon support corrosion in anti-oxidative Pt/C catalyst achieved via ionic liquid modification. Non-dispersive infrared spectroscopy measurements show that the carbon corrosion rate of Pt/C catalyst with more reduced state of Pt (Pt0) at 0.8 V is triple that of conventional catalyst. This indicates that high durability of Pt will exacerbate carbon corrosion, highlighting the necessity to co-optimize carbon and Pt stability for HDV catalysts design
