제목 Reversible Solid Oxide Fuel Cell for Synthetic Fuel Production from Steam and CO2
초록 Reversible solid oxide fuel cells (RSOFCs) also known as solid oxide electrolyzers (SOECs) have gotten much attention during the last decade because of the depletion of the fossil fuel and emission of the greenhouse gases. The present work was focussed on the development and performance evaluation of the Ni-YSZ/YSZ/LSM-73 cell for the electrochemical reduction of steam and CO2. Experiments were performed in the temperature range of 750-850 OC for both the SOFC and SOEC modes. The electrochemical performance of the cell was investigated in term of iV-curve and electrochemical impedance spectroscopy (EIS). At any temperature, a high current density was observed for H2 oxidation as compared to steam or CO2 reduction under the same magnitude of the applied potential.  However, the overall cell performance was found to be increased with temperature because of the favorable thermodynamics and kinetics conditions.  Moreover, a slight change in the area specific resistance (ASR) with time in the electrolysis mode operation of cell for 100 hours confirms the good stability of the Ni-YSZ cermet cathode under co-electrlysis conditions.
