Penyediaan Pelet Elektrolit Sr_0.6 Ba_0.4 Ce_0.9Ga_0.1O_3-δ Melalui Kaedah Glisina Nitrat bagi Aplikasi Sel Fuel Oksida Pepejal Konduktor Proton

The srceo_3-based electrolyte pellet is one of the most commonly used materials in electrolyte research since the introduction of proton-conducting solid oxide fuel cell at intermediate temperatures. electrolyte sr_0.6ba_0.4ce_0.9ga_0.1o_3-δ (sbcg) has been produced by the glycine-nitrate method as it is found to produce fine powders in a short time and support in lowering sintering temperatures. a systematic characterization has been carried out on the electrolyte powders to determine properties such as thermal decomposition (thermogravimetric analysis, tga), purity of the electrolyte powders (x- ray diffraction, xrd) and elemental analysis via x-ray energy distribution (edx). further, morphological characterization of the electrolyte pellets was conducted using scanning electron microscopy (sem). tga recorded the decomposition of the selective compounds was completed at a temperature of 1000°c. based on the three calcination temperatures of 900°c, 1000°c and 1100°c, the powders calcined at 1000°c were found to be eligible for the sintering process in the production of electrolyte pellet. this electrolyte pellet achieved a relative density of 99%. in addition, the pellet calcined at 1000°c also displayed distinctive grain boundary despite having a wide range of grain sizes. based on this study, sr_0.6ba_0.4ce_0.9ga_0.1o_3-δ has been shown to have great potential to be used as an electrolyte for the application of proton-conducting solid oxide fuel cells at intermediate temperatures.
