摘要: Abstract To investigate the application potential of Ce0.85(SmxNd1−x)0.15O2−δ(SNDC) (x=0.0, 0.2, 0.4, 0.6, 0.8, 1.0) as electrolytes for Intermediate-Temperature Solid Oxide Fuel Cells (IT-SOFC), single cells with identical electrode structures but using different were fabricated. Their performance was investigated under conditions. It found that cell SNDC (x=0.6) electrolyte had both highest Open Circuit Voltage (OCV) and maximum power density (MPD) 0.87 V 715 mW cm−2 at 600 °C, respectively. This can be mainly attributed to largest transference number oxygen ions conductivity (x=0.6). An anode functional layer (AFL) applied another cell, which used its electrolyte. Subsequently, a significant improvement in (the MPD 600 °C 980 mW cm−2) achieved.
