2011年6月30日 · In this work, we demonstrate a well designed bilayer GDC (∼6 μm)/YSZ electrolyte structure using a thin film approach, where the thickness of the YSZ layer is carefully controlled from ∼330 nm to ∼1 μm to explore the effect of YSZ thickness on the overall performance of the bilayer electrolyte cells.

2019年1月15日 · First successive deposition of YSZ and GDC is investigated which leads to the formation of bilayer structure. Then co-deposition of both compounds is carried out in order to obtain a chemical composition gradient, ensuring a smooth transition from the electrolyte to …

2021年10月5日 · Yttria-stabilized zirconia (YSZ)/gadolinia-doped ceria (GDC) dual-layered electrolytes have promising potential in solid oxide fuel cells (SOFCs) to prevent the destroying reaction of the lanthanum-containing cathode with ZrO 2 base electrolyte and improve ionic conduction by blocking ceria based electrolyte electronic conduction.

2020年1月1日 · Comprehensive ionic conductivity comparison is done for YSZ, ScSZ and GDC. YSZ, ScSZ and GDC each have an optimal operation temperature in SOFC applications. A brick layer model is used to predict the dependence of electrolyte resistance on grain size.

2020年8月25日 · 除先进镀膜工艺外，大多单电池通过丝网印刷在致密ysz表面制备gdc，但只能获得多孔隔离层。 致密的gdc隔离层可以有效降低燃料电池的欧姆阻抗，提高电池的导电率和催化性能。

2023年9月19日 · GDC（掺钆掺杂二氧化铈）可用作高性能 LSCF（La 0.6 锶 0.4 钴 0.2 铁 0.8 氧 3-δ）阴极和YSZ（8%摩尔氧化钇稳定氧化锆）电解质，以防止化学不相容和元素扩散。 然而，GDC层很难达到与YSZ电解质一样高的密度，特别是在低烧结温度下。 同时，将烧结温度提高到超过~1200 ℃会诱导 (Ce,Zr)O的形成 2 实在的方法。 在这项工作中，我们报告了在低烧结温度下制备的高致密双层 GDC/YSZ 电解质。 具体来说，将具有致密 YSZ 电解质的烧结阳极支撑 …

2023年5月19日 · In this work, we report a highly dense GDC/YSZ bilayer electrolyte prepared via cost-competitive method, at a relatively low sintering temperature. An ultra-thin and dense GDC barrier layer is grown on the surface of as-sintered YSZ electrolyte by twice successive in-situ hydrothermal growth at 180 o C.

沉积由of掺杂的CeO 2 （GDC）层（〜6μm厚度）和氧化钇稳定的ZrO 2 （YSZ）层组成的双层电解质，其厚度各不相同（〜330 nm，〜440 nm和〜1μm）。通过脉冲激光沉积（PLD）技术用于薄膜固体氧化物燃料电池（TFSOFC）。

The composite electrolytes for low-temperature solid oxide fuel cells were fabricated via coating the YSZ sol on tape-casted substrates of yttria doped ceria (YDC) and gadolinia doped ceria (GDC). The doped ceria substrates with 98% of relative density were prepared by the tape-casting method followed by the sintering at 1,500°C for 2 hours.
