Abstract:
Currently, fossil fuel dependent world's reservoirs are being used widely, so their availability is
reducing day by day along with contributing to global warming. As a result, interest in
sustainable energy is rising. The use of chemical looping technology and SOFCs are gaining
popularity as a strategy for cutting back on harmful gases that are discharged into the air when
fossil fuels are burned. In redox process of chemical looping, oxygen carriers play a significant
role in separating the CO2. Metal oxides as a provider of oxygen are appealing materials due to
their high stability and reactivity. A clean, pollution-free energy conversion method (chemical to
electrical) is offered by solid oxide fuel cells (SOFCs). This research will be focused on
developing multifunctional metal oxide (FexMn1-xO with SDC) cathodes material for SOFC and
as oxygen carrier for CLC by sol-gel and solid-state technique. These materials will be
characterized by X-Ray diffraction (XRD), Raman Spectroscopy, Electrochemical Impedance
Spectroscopy (EIS), Scanning Electron Microscopy (SEM), Fourier Transformation Infrared
Spectroscopy (FTIR). FTIR spectra represents molecular composition of prepared materials and
molecular bonding. Raman spectroscopy was performed to check vibrational modes and peak
shift behavior. X ray diffraction indicates the cubic crystal structure of given samples. Scanning
electron microscope analyze morphology of prepared material which confirms the pores on the
material surface shows homogeneous and drained structure. For thermal stability and redox
process, Thermogravimetric Analysis (TGA) will be used. The proposed fuel will be
Hydrogen/biogas for fuel cell performance chemical looping system.
