Produce solid oxide fuel cell anodes as (BaTiO3)100−x−(MgO)x for clean energy

Abstract

From the 20th century to the 21st century, many changes in climate conditions were occurred such as water disputes and high levels of industrial pollution. Besides, the generation of electricity depends on fossil fuels and oil. Therefore, this work attempted for a new challenge to transition away from fossil fuels, restrictions, and issues of both sustainable, renewable energy sources and move towards clean energy generation with fuel cells to alleviate air pollution problems which is an important environmental issue due to its effects on the quality of the atmosphere and public health of humans and other living organisms. So, the current experimental work made a new Cermet solid oxide fuel cell (SOFC) anode by changing the molar concentration of magnesium oxide-doped barium titanate with the formula of (BaTiO3)100−x−(MgO)x. The evaluation of these anodes was achieved physically, morphologically by field emission scanning electron microscopy (FESEM), mechanically by measure microhardness indentation, electrically by LCR meter, and statically by X-ray diffraction (XRD). The results indicated the significant effect of MgO as dopant by its impact effect on grain size, Vickers hardness (HV), and potentially other properties. The statistical analysis helped to determine the significance of these findings and provides insights into the optimal anode composition for the desired characteristics.
