Internal dry reforming of methane is envisaged as a possibility to reduce on capital and operation costs biogas fuelled solid oxide fuel cells (SOFCs) system by using the CO2 present in biogas. Due internal reforming, requirement for upgrading becomes obsolete, thereby simplifying complexity increasing its technology readiness level. However, impurities prevailing such H2S have been reported li...

Lanthanum strontium aluminum ferrite (La0.8Sr0.2Al0.2Fe0.8O3±δ-LSAF) perovskites are drawing attention as cathodes in solid oxide fuel cells (SOFCs). The structural properties of these materials mostly counting on the methods preparation. In this study, two different preparation namely hydrothermal and sol-gel were applied to prepare LSAF perovskite. characterization results including scanning ...

The necessity for experimental verification of leakage currents using Sm-doped ceria electrolytes (SDC) in solid-oxide fuel cells (SOFCs) has been indicated. This paper describes the theoretical limitations of Wagner's equation and details the analytical work that has been performed to support the experimental results. These limitations cannot be solved, even considering polarization voltage lo...

An increasing demand in the marine industry to reduce emissions led investigations into more efficient power conversion using fuels with sustainable production pathways. Solid Oxide Fuel Cells (SOFCs) are under consideration for long-range shipping, because of its high efficiency, low pollutant emissions, and fuel flexibility. SOFC systems also have great potential cater heat ships, but integra...

The main obstacle to solid oxide fuel cells (SOFCs) implementation is the high operating temperature in range of 800–1,000 °C so that it has an impact on costs. SOFCs work at temperatures causing rapid breakdown between layers (anode, electrolyte, and cathode) because they have different thermal expansion. study focused reducing medium range. SmBa0.5Sr0.5Co2O5+δ (SBSC) was studied as a cathode ...

Solid oxide cells (SOCs) including solid fuel (SOFCs) and electrolysis (SOECs) are advanced electrochemical energy storage conversion devices. However, the lack of highly active stable electrode materials impedes their practical applications. Herein, in-situ exsolved CoFe nanoparticles on perovskite matrixes with abundant defects developed as bifunctional electrocatalysts for SOCs from Sr2FeMo1...

High power density operation is essential for cost reduction in solid oxide fuel cells (SOFCs), and thus the present work proposes a highly active Gd0.5Sr0.5CoO3−δ (GSC) Ce0.8Gd0.2O1.9 (GDC) nanocomposite cathode intermediate-temperature SOFCs. Its structure formed by using GSC-GDC particles synthesized via spray pyrolysis, which produces uniform-sized secondary consisting of nano-sized GSC GDC...
