Measuring individual components of a fuel cell under heat and pressure is a challenge. The best technique, X-ray photoelectron spectroscopy (XPS), could only be used in a vacuum -- until now, that is. A working solid oxide electrochemical device operating at 750 degrees Celsius has been studied in detail for the first time.
