Abstract

In this communication an analysis of Pt catalyst morphology evolution in high temperature fuel cells subjected to different load cycles using synchrotron Small Angle X-ray Scattering (SAXS) and Grazing Incidence Small Angle X-ray Scattering (GISAXS), is presented. The measurements show the aggregation of the Pt nanoparticles (NPs) in used MEAs with respect to a reference new MEA. Moreover, the anode and cathode sides of all MEAs present different Pt NPs size whose morphological characteristics can be separately determined using GISAXS.
