Structure-to-property relationships in fuel cell catalyst supports: Correlation of surface chemistry and morphology with oxidation resistance of carbon blacks

► Durability of modified carbon black as PEMFC catalyst supports is studied. ► Statistical structure-to-property relationship is built by PCA. ► Surface chemistry, physical properties and microscopic structure are analyzed. ► DIP of SEM images extracts roughness, texture and shape parameters. ► Wettability is a critical parameter in designing stable supports.
