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.
