半导体离子型纳米复合电解质材料GDC-LCNC的性能研究
Study on the Performance of Semiconductor-ion Nanocomposite Electrolyte Materials GDC-LCNC
【摘要】 制备了具备高离子电导率的半导体离子型纳米复合电解质材料GDC(Gd0.9Sm0.1O1.95)–LCNC(LiCo0.225Ni0.7Cu0.075O3-δ),并与纯GDC进行对比,研究了m(GDC)∶m(LCNC)对电池性能的影响。结果表明:纯GDC电解质材料电池性能最差,无电流;m(GDC)∶m(LCNC)为2∶1时,获得的复合电解质材料最大功率密度为223 mW/cm2;m(GDC)∶m(LCNC)为3∶1时,复合电解质材料的综合性能最佳,且在定电压(0.45 V)时,短时(4 h)内电流密度无明显衰减。
【Abstract】 Semiconductor ionic nanocomposite electrolyte materials GDC(Gd0.9Sm0.1O1.95)-LCNC(LiCo0.225Ni0.7Cu0.075O3-δ) with high ionic conductivity were prepared, while the effects of the mass ratio between GDC and LCNC on the performance of the fuel cell were studied. Results show the fuel cell with pure GDC electrolyte has the worst performance without current. When the mass ratio is 2∶1, the maximum power density would be 223 mW/cm2. Optimum comprehensive performance is to be obtained for the cell at the mass ratio of 3∶1, when the current density does not reduce significantly within a short time(4 h) at the constant voltage of 0.45 V, indicating good performance of the GDC-LCNC.
