【摘要】 研究了反应磁控溅射（magnetron sputtering）技术制备的纳米厚度YSZ电子阻隔层对以GDC为电解质的低温固体氧化物燃料电池性能的影响。通过对YSZ隔层的物相分析、形貌观察,探究了不同基底溅射温度对YSZ隔层的影响。随着基底溅射温度的升高,YSZ隔层的针状孔洞减少,说明高温溅射有利于制备与GDC电解质膜结合良好的薄膜。在550℃下电池的V_OCV（开路电压）提升了0.04 V,最大功率密度提升了24%。结果表明磁控溅射沉积的电子阻隔层能够有效阻隔电子电导,提升电池的开路电压。更多还原

【Abstract】 The effect of a nano-scale YSZ electronic barrier layer prepared by reactive magnetron sputtering technology on the performance of low-temperature solid oxide fuel cells with GDC as electrolyte was studied.Through the phase analysis and morphology observation of the YSZ electron barrier layer,the influence of different substrate sputtering temperatures on the YSZ electronic barrier layer was explored.As the substrate sputtering temperature increased,the pin holes in the YSZ barrier layer was reduced,and the YSZ layer was well bonded to the GDC electrolyte.The results indicate that high-temperature sputtering is beneficial to the preparation of the YSZ film.Under 550 ℃,the V_OCV increases by 0.04 V,and the maximum power density increases by 24%.It shows that the electron barrier layer deposited by magnetron sputtering can effectively block the electronic conduction and increase the open circuit voltage of the cell.更多还原
