In this research, CeO2 was doped with samarium to produce Samarium doped-Ceria, SDC, then composited with sodium carbonate to produce NSDC. Two types of NSDC had been prepared, i.e., NSDC1 and NSDC2, corresponding to different methods of incorporating sodium carbonate which were without and with pre-heating procedures, respectively. The ionic conductivity of NSDCs at 300 °C to 600 °C was calculated by measuring the impedance at 20 Hz to 5 MHz. The results showed that additions of sodium carbonate for NSDC1 eliminate electronic conductivity of SDC at 600 °C; however, it reduces ionic conductivity. NSDC2 did not provide good ionic conductivity, although this electrolyte showed electronic conductivity at given temperatures. This indicates that NSDC2 is not suitable for electrolyte but more suitable for electrode material. Stability measurements on a single cell of NSDC1|NSDC|NSDC revealed that the addition of sodium carbonate can inhibit diffusion of electrode’s elements into the electrolyte, which could increase fuel cell stability.
