This database encompasses a wide range of experimental data related to single solid oxide fuel cells (SOFCs): thousand-hour long-term stability tests; I-V-P (current-voltage-power) curves of single cells before and after the long-term stability test; corresponding electrochemical impedance spectroscopy (EIS) measurements before and after the stability test; transmission electron microscopy (TEM) and high-resolution TEM (HRTEM) images of the interior of single cell electrolytes; STEM-EDS (scanning transmission electron microscopy-energy dispersive X-ray spectroscopy) elemental mapping of grains and grain boundaries within the electrolyte; TEM images of nickel-phase particles; scanning electron microscopy (SEM) images of battery cross-sections; I-V-P curves and EIS measurements of batteries at various temperatures; and experimental data on the time-dependent growth rates of polarization resistance including ohmic resistance.

The SOFC test setup and power generation system are generally configured with heating and thermal management systems, gas supply systems, reforming systems, battery power generation subsystems, control systems, exhaust pipelines, safety detection systems, and other auxiliary components. The performance testing instruments include external electronic loads and related devices. Anode fuel gas is supplied from gas cylinders or pipelines, while cathode air is provided by fans. The anode and cathode gases pass through a gas supply system equipped with metering devices, enter a preheating unit to be heated to a specified target temperature, and then flow into the anode and cathode sides of the cell stack respectively to undergo electrochemical reactions and generate electric current. The SOFC single cells are tested and monitored using the external electronic load to evaluate their electrochemical performance.
