Characterisation and Electrochemical Properties of Ce0.8Sr0.2Fe0.9Ir0.04Co0.06 (CSFIC) Cathode Material for Application in Low Temperature SOFC

Abstract

In this study, the cathode Ce_0.8Sr_0.2Fe_0.9Ir_0.04Co_0.06 perovskite material was prepared by sol-gel technique and then tested for its characteristic application in solid oxide fuel cell. The textural properties were tested using X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy. The morphology was examined using scanning electron microscopy and high resolution transmission electron microscopy. The electrochemical properties were measured using Kittec Squadro muffle furnace from Fiaxell SOFC technologies connected to a Nuvant ^TM potentiostat and galvanostat. These properties were tested for its potential application in low temperature solid oxide fuel cells within 300 -500 °C. It exhibited a current density of 801.90 mA/cm², a power density of 471.59 mW/cm² and an area specific resistance (ASR) of 0.349 Ω/cm².
