Preparation of Ce0.8Sm0.2O1.9 Thin Films by Electrophoretic Deposition and their Fuel Cell Performance

Article Preview

Abstract:

Ce0.8Sm0.2O1.9 (Samaria-doped ceria: SDC) precursors were synthesized by carbon-assisted spray pyrolysis. SDC thin films were prepared by electrophoretic deposition using the SDC precursor particles. The as-prepared SDC thin films were sintered at 1600 °C for 10 h. Uniform films with a thickness of approximately 20 μm were obtained. A fuel cell using the prepared thin films showed a maximum power density of 60.6 mW/cm2 and an open circuit voltage (OCV) of 0.63 V at 700 °C.
