A novel in-situ/operando electrochemical cell for doing Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS) studies was developed. The cell allows treating the electrode surface with various preparation techniques such as sputtering and deposition as well as analyse it by XPS and other complementary characterisation methods. The electrode is covered under full electrochemical control by a nanoscopic electrolyte layer. This allows in-situ/operando investigations of electrochemical reactions such as oxygen reduction or oxide reduction by ambient pressure XPS. Examples will be presented and discussed in detail.
