Abstract

Porous Ni–Al–CGO cermet (CGO = Сe_0.9Gd_0.1O₂) for use in solid oxide fuel cells was fabricated by thermal explosion (volume reaction) in Ni–Al–CGO powder compacts in different heat sink conditions. Temperature profiles of thermal explosion were recorded and analyzed as a function of green composition. Phase composition of resultant porous materials was found to depend on the CGO content of green mixture and temperature of vacuum annealing. Starting and final materials were characterized by XRD, SEM, and EDS. Synthesized uniform cermets with a porosity of 50–60% can be recommended for use as a support for solid oxide fuel cells with Ni/CGO anode.

用于固体氧化物燃料电池的多孔Ni–Al–CGO金属陶瓷

摘要

多孔镍铝-CGO陶瓷（CGO =Сe _0.9的Gd _0.1 ø ₂）在固体氧化物燃料电池中使用由在不同散热条件的Ni的Al-CGO粉末压块热爆（体积反应）制造。记录并记录热爆炸的温度曲线，并将其作为绿色成分的函数。发现所得多孔材料的相组成取决于生坯混合物的CGO含量和真空退火的温度。起始物料和最终物料均通过XRD，SEM和EDS进行了表征。建议将孔隙率为50–60％的合成均匀金属陶瓷用作带有Ni / CGO阳极的固体氧化物燃料电池的载体。
