The materials comprising polymer electrolyte membrane fuel cells (PEMFCs) offer a host of imaging challenges, spanning wide length scales and materials classes. Issues of beam sensitivity are greatly magnified when scanning transmission electron microscopy (STEM)-based spectroscopic techniques, such as electron energy loss spectroscopy (EELS) or energy dispersive X-ray spectroscopy (EDS), are employed. This work will present our investigations in mitigating beam artefacts in the study of PEMFC catalyst layers.
