Synthesis and Characterization of PrNiO3 Perovskite with Various Ratios of Gelatin as Cathode of Solid Oxide Fuel cell

This article focuses on perovskite materials for their application as a cathode material in solid oxide fuel cells(SOFC). Perovskite-type oxides, such as PrNiO3, is one of the material invistigated as a cathode of SOFC. In this study PrNiO3 oxide composition was prepared by using gelatin powder in various ratios of gelatin without using high oxygen pressure and long-time calcination. The obtained powder was calcined at 700 , 800 and 900 for 4h and then it was characterized using X-ray diffraction pattern and Fourier Transform Infrared (FTIR) spectroscopy. XRD patterns showed that structure calcined at 900 was the best one in tems of the formation of single phase perovskite. FTIR spectra showed that some impurity peaks disappeared whit increasing temperature. A substance which is obtained from this method could create a material ideal for fuel cell applications.
