Study of a Perovskite Oxides structures as electrolyte for proton conducting solid oxide fuel cell

What is it about?

A promising option for producing energy sustainably is the Solid Oxide Fuel Cell (SOFC), which generatespower in an environmentally benign and very cost-effective manner. SOFCs appear as a practical substitute as Bangladeshstruggles with issues including depleting natural gas reserves and pollution from conventional fuel sources. With anemphasis on synthesis and structural characterization, a new family of materials, Ba1-xNaxCe0.7Zr0.1Y0.15Zn0.05O3-δ (x = 0.1,0.3 & 0.5) perovskite oxides, aresynthesized in this study. The samples were made using conventional solid-state sinteringtechniques, which involved 4 hours at a final sintering temperature of 1400°C. The synthesized materials were analyzedusing characterization techniques like X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-rayfluorescence (XRF). For x = 0.1, XRD shows cubic structure. SEM images convey highly dense materials for allcompositions. To appraise thermal stability differential scanning calorimetry (DSC) was conducted. These results pave theway for more research into the possible uses of these synthetic perovskite oxide materials, particularly in Solid Oxide FuelCell technology, by providing a deeper knowledge of their structural characteristics and thermal behavior.

Why is it important?

Applications: Combined Heat and Power: SOFCs can efficiently generate electricity while capturing waste heat for other uses like heating buildings or industrial processes. This combined approach maximizes energy utilization and reduces overall energy consumption. Micro Combined Heat and Power: Smaller-scale SOFC systems can provide electricity and heat for individual homes or small businesses, promoting localized energy production. Distributed Generation: SOFCs can be used as distributed generators within power grids, offering flexibility and resilience by diversifying power sources and reducing reliance on centralized power plants. Auxiliary Power Units: SOFCs can replace diesel generators in trucks and other heavy-duty vehicles, significantly reducing emissions and fuel consumption. Range Extenders for Electric Vehicles: SOFCs can act as range extenders for EVs, providing additional power and extending their driving range without relying solely on battery charging.
