Measuring Solid Oxide Cell Electrochemical States

Caption

Using an electrostatic lens, the APXPS detector collects photoelectrons emitted from the surface of the sample by the x-ray beam. Chemical states (green circles) and electric potentials (red squares) are measured locally. The greatest activity was measured where the electrode (green) met the electrolyte (blue).
