Abstract

Tailoring nanostructure of the electrocatalyst layer is of technological relevance for future generation Polymer Electrolyte Fuel Cells (PEFCs). Since the porous nanostructure allows the transport of reactant gas, water vapor, protons, and electrons, quantitative optimization of nanostructure is essential. In this study, quantitative evaluation of the porous electrocatalyst layers using different support materials is carried out by applying various image processing procedures using the focused-ion-beam coupled scanning electron microscopy (FIB-SEM) and thresholding methods. Thresholding processes can be applied to various types of electrocatalyst nanostructures by detecting intensity contrast changes around pore edges.
