Herein, we introduce the characteristic constrictions size as a descriptor for microporous layers (MPL). This parameter is calculated by volumetric analysis of focused ion beam nanotomography and compared to mercury intrusion porosimetry measurements.Chemistry, MultidisciplinaryChemistrymicrostructure-property relationshipsfuel-cellsmicroporous layerwater transportliquid watertortuositymorphologygdltext::journal::journal article::research article
