中文摘要：

固体氧化物燃料电池（SOFC）及其组元的低温制备有利于材料和电池性能的优化,降低制备成本。立方相的全致密氧化钇稳定氧化锆（YSZ）电解质是SOFC中最通用的电解质。传统的烧结工艺需要在1 400—1 450℃才能实现YSZ电解质的致密,而使用纳米粉体和三步烧结工艺可以在1 200—1 300℃得到致密电解质。氧化钪稳定氧化锆（ScSZ）电解质可以使用3nm的粉体在900℃下致密化,氧化钆掺杂的氧化铈可以通过加入烧结助剂在800℃下实现致密化烧结,这些工艺已广泛用于SOFC制备。SOFC的低温制备工艺可有效推进SOFC的产业化。

英文摘要：

The manufacturing of solid oxide fuel cell （SOFC） and its main components at low temperature are very important to optimise the performance of material, cell and lower the cost. The cubic full dense yttria stabilized zirconia （YSZ） electrolyte, one of the most popular electrolyte in SOFC, is obtained by three-step sintering process at 1 200--1 300~ from nano powders, which needs to be dense at 1 400--1 450~ by traditional sintering process. The scandia stabilized zirconia （ScSZ） and gadolinia doped ceria （GDC） electrolytes are sintered to be full dense respectively at low temperature of 900~C and 800~C from 3nm powders of ScSZ and by sintering additives, which, now, are widely used in SOFC process. The low temperature process of SOFC would be benefit to put forward SOFC commercial ization in the market.
