Abstract:percentage of 1% were impregnated on the cathode surface of solid oxide electrolysis cell named La0.55Sr0.45Fe0.85Mo0.15O3(LSFM) by the impregnation method. The effect of impregnation on the electrocata⁃lytic reduction of CO2by parent perovskite was analyzed. The results indicate that compared with theLSFM cathode, the current density of the LSFM cathode with 1% of Ir (LSFM/Ir) is increased by 25%and its polarization resistanceRpis only 27% of that of the LSFM. The Ni-Fe nanoparticle alloy formedon the surface of the LSFM cathode with 1% of Ni (LSFM/Ni) can significantly improve the anti car⁃bon deposition ability of the cathode. Close-
