Abstract

Sm-doped CeO2-Sm0.2Ce0.8O1.9 (SDC) electrolyte powders were prepared by using glycine-nitrate process, solid-state process and citric-nitrate process, respectively. These three kinds of SDC powders were deposited onto the NiO-SDC anode substrates by colloidal spray coating technique. The single cell was completed after screen printing the BSCF cathode on the SDC electrolyte film. The performance of the single cell was tested by the CHI604B electrochemical work station. The granularity distribution of the SDC powders was analyzed by the HORIBA LA-920 and the microstructure of the cell was investigated by SEM. Results show that SDC electrolyte powders made by citric-nitrate process is content with the colloidal spray coating technique for SOFCS.
