data repository contains the data sets associated with the manuscript <strong>'Electrochemical Performance and Durability of High-Temperature Solid Oxide Electrolysis Cells with SFM and SFM-GDC Fuel Electrodes for Hydrogen and Syngas Production'</strong>. Published in <i>J. Mater. Chem. A</i> <a href = 'https://doi.org/10.1039/D5TA04819B'> link </a> <br><br> Motivation: The increasing need to valorize emitted CO2 and close the carbon cycle through the production of synthesis gas, fuel, and hydrogen has driven the development of high-temperature electrolysis technology. SOEC offers a promising solution with its ability to produce pure H2 at elevated temperatures (650°C-900°C) without the use of precious metal catalysts, making it cost-effective and more efficient than low-temperature technologies like alkaline and polymer exchange membrane cells due to advantageous kinetics and thermodynamics. By utilizing pre-existing chemical industry heat, SOEC can achieve high electrical efficiencies of up to 100%. The long-term stability and performance of current Ni-based fuel electrodes is preventing the wide industrial implementation though, prompting the search for alternative Ni-free materials with good electrochemical performance and long-term stability, such as perovskite fuel electrodes like Sr2FeMoO6-δ (SFM). <br><br> Central Research Question: In this work, solid oxide electrolysis cells with SFM and the composite ceramic-ceramic (cercer) SFM-GDC fuel electrode materials were investigated in steam- and co-electrolysis conditions for the first time, regarding performance and long-term stability of up to 500 h in 50% steam and 50% H2. <br><br> Description of folder contents (switch to tree view): <br> <li>01_In Situ Transmission Electron Microscopy: Contains the taken TEM Images taken and the experimental procedure. </li> <li>02_X-Ray Diffraction_Temperature_Atmosphere Variation: Contains raw data files of the XRD measurements, the TOPAS6 fit criteria, the Rietveld Report as well as the data over the whole in operando Experiment. </li> <li>03_X-Ray Photoelectron Spectroscopy: Contains the raw data and the data evalution for the measurements in air and after reduction in H2.</li> <li>04_Powder_Scanning Electron Microscopy: Contains the SEM Image of the unreduced and reduced sample.</li> <li>05_Conductivity Measurement: Contains the raw data for SFM and SFM-GDC conductivty measurements in air and in H2.</li> <li>06_Transmission Electron Microscopy: Contains the Image of one exsoluted nanoparticle observed for SFM.</li> <li>07_Electrochemistry_Initial Performance Characterization: Contains the raw data of the initial AC and DC characterization of the cells with an SFM and an SFM-GDC fuel electrode.
