摘要 合成了复合电解质Sn0.85Ga0.15P2O7/聚苯醚(Sn0.85Ga0.15P2O7/PPO)。通过X射线衍射仪(XRD)和扫描电镜(SEM)对产物进行分析,XRD结果表明Sn0.85Ga0.15P2O7和PPO复合没有发生反应生成新物质,SEM结果表明样品致密性良好。采用电化学工作站对Sn0.85Ga0.15P2O7/PPO的中温电性能(100~350℃)进行了研究。电化学结果表明,湿润氧气气氛中Sn0.85Ga0.15P2O7/PPO在300℃即可达到最大值1.2×10-2S/cm。其在300℃开路条件下的电解质阻抗、极化阻抗分别为8.69和0.51Ω·cm2。H2/O2燃料电池性能测试表明,在0.54V时有最大输出功率密度60.5mW/cm2

Abstract: Firstly,the new organic-inorganic composite electrolyte PPO/Sn0.85Ga0.15P2O7 was prepared.XRD showed that there were only peaks corresponding well to Sn0.85Ga0.15P2O7,without any formation of other substances.SEM images showed that the electrolyte was sufficiently dense.The intermediate temperature conduction behavior was investigated by AC impedance spectroscopy in the temperature range of 100~350℃.The highest conductivity was observed to be 1.2×10-2 S/cm for SG15P-PPO in wet oxygen at 300℃.The ohmic resistance and interfacial polarization resistance of SG15P-PPO at 300℃ under open circuit condition was 8.69Ω·cm2 and 0.51Ω·cm2,correspondingly.The H2/O2 fuel cell generated the maximum power density of 60.5mW/cm2 at 0.54V.
