Oxygen reduction reaction: In this work, we studied the influence of the mesopore structure of the carbon support material towards MEA cell performance under dry and wet operating conditions. ECSA and oxygen mass transport within the catalyst layer are directly linked to the accessibility and pore openings of the supporting material.
