摘要

采用流延法制得LSCM-YSZ阳极支撑层/Ni-ScSZ阳极活性层/ScSZ电解质层复合膜,在LSCM-YSZ支撑层上印刷一层Cu-LSCM-CeO2阳极催化层,即Cu-LSCM-CeO2/LSCM-YSZ/Ni-ScSZ功能梯度层阳极. 研究表明,Cu/LSCM/CeO2质量配比为2:7:1功能梯度阳极(LSCM-YSZ2010)有较好的性能,单电池以氢气和乙醇为燃料(750 oC)最大功率密度分别为511和390 mW?cm-2,单电池稳定性实验表明,LSCM-YSZ2010阳极单电池以乙醇为燃料750 oC长时间运行218 h,性能稳定. X-射线能量散射分析表明该阳极具有较好的抗碳沉积性能.

Abstract

Solid oxide fuel cell (SOFC) directly operating on hydrocarbon without external reforming has the potential of greatly speeding up the application of SOFCs for transportation. In this paper, a three-layer structure anode was fabricated by tape casting and screen printing method. The addition of Cu-LSCM-CeO2 to the supported anode surface presented better performance running on H2 and ethanol. The maximum power densities were 511 and 390 mW?cm-2, respectively, running on H2 and ethanol at 750 °C. No significant degradation was observed on the anode. Consequently, the Cu-LSCM-CeO2 catalyst layer on the surface of the LSCM-YSZ support layer makes it possible to have good stability for long-term operation in ethanol fuel due to free carbon deposition.
