چکیده انگلیسی
The use of active perovskite material as both the cathode and anode in reversible solid oxide cells (RSOCs) is of increasing interest. In this work, a nominated Sr2Fe1.5Mo0.5O6âδ (SFM) is deposited onto porous Y0.16Zr0.84O2âδ (yttria-stabilized zirconia) backbone via an infiltration process. The apparent conductivity and conductivity of the infiltrated SFM are investigated at 600-750â¯Â°C, towarding a series of infiltration loadings, which increase with the SFM loading. However, the area specific resistance shows the lowest value, e.g., 0.153â¯Î© cm2 at an optimal loading of 9.53â¯wt% in 1:1 CO-CO2 while 0.064â¯Î©â¯cm2 at 11.67â¯wt% in air. In fuel cell mode, the two corresponding cells exhibit good performance that the maximum power densities are 218 and 265â¯mWâ¯cmâ2, respectively. In electrolysis mode, the current densities show 0.573 and 0.618â¯Aâ¯cmâ2 when 1.5â¯V is applied. These results reveal that SFM would be promising as RSOC electrodes.
