【Abstract】

For the planar anode-supported solid oxide fuel cell with Ni-YSZ anode, YSZ electrolyte was prepared by aqueous tape casting and La 2O 3 was impregnated into the Ni-YSZ anode. Traditional composite LSM-YSZ was used as the cathode. Microstructure and composition of the single cell were measured by scanning electron microstrscope (SEM) and energy dispersive spectra (EDS). When using ethanol/steam as fuel, the power density and impedance spectra of the single cell were measured by cyclic voltammetry and AC impedance method at 750 °C. The results showed that impregnated La 2O 3 particles with size of 90 nm were distributed uniformly around the pores of the anode. The single cell with impregnated La 2O 3 exhibited more stable performance than the cell without impregnated La 2O 3. With the increase of loading of La 2O 3, the single cell showed better performance and better anti-carbon deposition ability. The results show that the degradation rate of the single cell is 0.09%/h after operating at 7 h with the La 2O 3 loading of 2.4 wt%.
