SrCeO₃ and SrCe 0.9 Sm 0.1 O 3-α were synthesized using a high-temperature solid-state reaction method using Sm₂O₃, SrCO₃, CeO₂ as precursors, then the SrCe 0.9 Sm 0.1 O 3-α -NaCl-KCl composite electrolyte was fabricated by compounding SrCe 0.9 Sm 0.1 O 3-α with NaCl-KCl and sintering it at a lower temperature (750 °C) than that of a single SrCeO₃ material (1540 °C). The phase and microstructure of the samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The conductivities of the samples were measured in dry nitrogen atmosphere using electrochemical analyzer. The conductivities of the SrCeO₃, SrCe 0.9 Sm 0.1 O 3-α and SrCe 0.9 Sm 0.1 O 3-α -NaCl-KCl at 700 °C were 2.09 × 10 -5 S·cm -1 , 1.82 × 10 -3 S·cm -1 and 1.43 × 10 -1 S·cm -1 respectively. The conductivities of SrCe 0.9 Sm 0.1 O 3-α -NaCl-KCl composite electrolyte are four orders of magnitude higher than those of SrCeO₃ and two orders of magnitude higher than those of SrCe 0.9 Sm 0.1 O 3-α . The result of log σ ~ log p O₂ plot indicates that SrCe 0.9 Sm 0.1 O 3-α -NaCl-KCl is almost a pure ionic conductor. The electrolyte resistance and the polarization resistance of the H₂/O₂ fuel cell based on SrCe 0.9 Sm 0.1 O 3-α -NaCl-KCl composite electrolyte under open-circuit condition were 1.0 Ω·cm² and 0.2 Ω·cm² respectively. Further, the obtained maximum power density at 700 °C was 182 mW·cm -2 .
