摘要：Solid oxide fuel cells(SOFCs)have attracted a great deal of interest because they have the highest efficiency without using any noble metal as catalysts among all the fuel cell ***,traditional SOFCs suffer from having a higher volume,current leakage,complex connections,and difficulty in gas *** solve these problems,Rolls-Royce has fabricated a simple design by stacking cells in series on an insulating porous support,resulting in the tubular segmented-in-series solid oxide fuel cells(SIS-SOFCs),which achieved higher output *** work systematically reviews recent advances in the structures,preparation methods,perform-ances,and stability of tubular SIS-SOFCs in experimental and numerical ***,the challenges and future development of tubular SIS-SOFCs are also *** findings of this work can help guide the direction and inspire innovation of future development in this field.

摘要：根据三峡地下电站主变采用的自粘半硬换位导线技术要求,为更好地满足线圈绕制需要,采用铜导体二次改拔新工艺成功实现了高屈服强度漆包扁线制造。经过对大量的导电漆的查询、试验、筛选与比对,找到了适应变压器运行环境的屏蔽悬头导电材料。通过自主创新和优化设计,制定了具有特殊结构的带屏蔽芯自粘换位导线制造的工艺方法和生产流程。根据大截面多线芯换位导线的特点,改进了工艺方法,顺利实现了换位升层,防止了导线变形和受损。
