Chemical Fingerprint Associated with the Formation of Pt in the Membrane in PEM Fuel Cells
Abstract
In this study, localized chemistry around Pt crystals formed in the membrane in an end-of-life (EOL) fuel cell catalyst coated membrane (CCM) was studied using near edge X-ray absorption spectra (NEXAFS) recorded with scanning transmission X-ray microscopy (STXM). X-ray Photoelectron spectroscopy (XPS) was applied to analyze the composition of the cathode catalyst powder used to prepare the CCMs. The XPS data indicated the presence of …
