We describe a fabrication strategy for preparing yttria-stabilized zirconia nanotube (YSZ-NT) arrays embedded in porous alumina membranes by means of template-directed atomic layer deposition (ALD) technique. The individual YSZ-NTs have a high aspect-ratio of well over 120, about ~ 110 nm in diameter, and ~ 14 µm in length. Interfacing the tube arrays with porous Pt was also introduced on the basis of partial etching technique in order to construct Pt/YSZ-NTs/Pt membrane electrode assembly (MEA) structures. The resulting YSZ-NTs MEAs show a 7 mm in diameter with a roughness factor of ~ 2. Area specific resistance was measured up to 1.84 Ω cm at 400 °C using H as fuel.
我们描述了一种通过模板导向原子层沉积（ALD）技术制备嵌入多孔氧化铝膜中的氧化钇稳定氧化锆纳米管（YSZ-NT）阵列的制造策略。单个YSZ-NT具有远超过120的高纵横比，直径约为110nm，长度约为14μm。为了构建Pt/YSZ-NTs/Pt膜电极组件（MEA）结构，还基于部分蚀刻技术引入了使管阵列与多孔Pt接触。所得的YSZ-NTs MEA直径为7mm，粗糙度因子约为2。在400°C下以H作为燃料时，面积比电阻测量高达1.84Ω·cm。
