Overview

Demonstrates enhanced performance and durability of PEMFCs through a protective PANI/CeOx layer, suggesting improved commercial viability.

Key Points

  • The research aims to enhance the performance and durability of proton exchange membrane fuel cells using an integrated membrane electrode assembly.
  • Developed an integrated MEA fabrication strategy using a full spray-coating method.
  • Incorporated a polyaniline/cerium oxide (PANI/CeO x ) protective layer.
  • Conducted testing under H 2 /O 2 conditions for performance evaluation.
  • After 150 hours of operation, the open-circuit voltage declined by less than 10%.
  • Achieved a peak power density of 2.04 W cm -2 at 80 °C and 100% relative humidity.
  • Improved long-term stability through effective radical scavenging and enhanced membrane-catalyst adhesion.
