ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.
