摘要：

When the solid oxide fuel cell uses ethanol as fuel, it is highly prone to cause carbon deposition and cell failure in the traditional Ni-based ceramic anode. Herein, Ni0.9Cu0.1 TiO3-$ catalytic reforming layer is coated on the surface of the traditional Ni-based anode to address this issue. It has been shown that the reforming layer of Ni0.9Cu0.1TiO3-$ decomposes into Ni-Cu alloy and TiO2 under reducing atmosphere, which significantly improves the coking resistance performance of the anode. Cells with Ni0.9Cu0.1TiO3-$ layer have excellent electrocatalytic performance, and the maximum power density can reach 867 mW cm-2 at 800 degrees C using ethanol as fuel. Moreover, it doesn't show significant degradation in the 50h stability test, proving that the Ni0.9Cu0.1TiO3-$ reforming layer has good coking resistance performance and electrocatalytic activity when used in direct ethanol solid oxide fuel cells.
