Overview

This analysis shows improved mass activity of 0.54 A mg−1 in fuel cells, highlighting the effectiveness of the Co–N–C support with L1 0‐PtCo alloy.

Key Points

  • The catalyst delivers a mass activity of 0.54 A mg−1, which is 6.3 times greater than carbon-supported PtCo.
  • Testing shows improved peak power density while using only 60 µg Pt cm−2, significantly reducing material costs.
  • Durability testing reveals minimal performance loss after 30,000 voltage cycles, indicating exceptional robustness under operational conditions.
  • The unique mesoporous structure of the Co–N–C support enhances mass transport, crucial for optimal fuel cell functionality.
