【Abstract】 Gd_0.1Ce_0.9O_1.95（GDC）, La_0.45Ce_0.55O_2-σ/2（LDC） and La_0.9Sr_0.1Ga_0.8Mg_0.2O_2.85（LSGM） electrolyte materials were synthesized by the citric method. Anode-supported single cells with GDC-LSGM, LDC-LSGM and LDC-LSGM-LDC multi-layer thin film electrolyte were prepared. The U-J characteristics and output power performance of the single cells were measured. The results showed that no current could be taken from the cell with GDC-LSGM electrolyte.The cell with LDC-LSGM electrolyte gave the maximum output power density of 0.72 W/cm² at 800 ℃, but it was not stable. The open circuit voltage of the cell with LDC-LSGM-LDC electrolyte was the highest, reaching to 0.814 V at 800 ℃.更多还原
