Abstract

To investigate ECSA degradation in PEM fuel cells, we applied a range of voltage-cycling profiles in a H₂/N₂ atmosphere to multiple MEAs. A novel experimental setup is implemented using a multichannel potentiostat, enabling:
• Independent control of aging protocols on each single cell
• Parallel testing of multiple MEAs under varied conditions
• High-throughput degradation analysis
This approach allows for rapid, comparative insights into material durability across different catalyst and membrane configurations.
