Tailoring Pt-Support Interactions via Mn-Nx Coordination for Enhanced Phosphoric Acid Tolerance in HT-PEMFC Cathodes

LZLi ZhangDXDengzui XuJSJiawei Shi

Key Points

  • The aim is to improve the performance and durability of cathodes in high-temperature PEM fuel cells by mitigating the effects of phosphoric acid.
  • Investigated the interaction between phosphoric acid and platinum sites in the catalyst layer.
  • Explored Mn-Nx coordination to enhance support interactions.
  • Assessed the kinetics of the oxygen reduction reaction under high-temperature conditions.
  • Demonstrated that modified support structures can reduce phosphoric acid binding to platinum.
  • Showed improved oxygen reduction reaction kinetics compared to standard setups.
  • Increased durability of cathodes under phosphoric acid exposure was observed.

Abstract

Phosphoric acid (PA) diffused from membrane to the cathode catalyst layer and its irreversible binding to Pt sites critically deteriorate the oxygen reduction reaction (ORR) kinetics and durability of high-temperature...
