Solid oxide fuel cells (SOFCs) are an effective and sustainable energy conversion technology. As operating temperatures decrease, metal interconnects and supports are widely employed in SOFCs. It is critical to apply a protective coat on ferritic stainless steel (FSS) to suppress Cr evaporation and element interdiffusion under high temperatures. El...

Nickel (Ni) film on patterned Ni- yttria-stabilized zirconia (YSZ) anode shows dynamic spreading and splitting during solid oxide fuel cell (SOFC) operation, where wettability of Ni on YSZ is greatly enhanced (Z. Jiao, N. Shikazono, J. Power Sources 396 119–123, 2018). In the present study, a physics-informed neural network (PINN) constrained by Ca...

The development of cathodes with improved polarization, aimed at reducing the operating temperature of solid oxide fuel cells (SOFCs), is an important avenue of research toward more efficient SOFCs. Sr(Ti0.3Fe0.7)O3–δ recently emerged as an active and stable cathode material; although its oxygen transport capability was shown to be further improved...

Ni- yttria-stabilized zirconia is commonly used as a fuel electrode cermet in solid oxide cells due to its compelling combination of conductivity, stability, and material compatibility. However, it faces significant degradation when exposed to hydrocarbon-rich fuels, such as tar-containing biogas. Carbon adsorption poisons the Ni component, leading...

The chemical composition of the cathode material influences the performance of the low temperature solid oxide fuel cells (SOFCs). In the present work, two different cathode materials (Ba0.5Sr0.5Co0.2Fe0.8O3 and Ba0.5Sr0.5Mg0.2Fe0.8O3) were prepared to assess the role of Mg in the place of Co on the performance of the SOFC. Symmetric cells were fab...

A solid oxide fuel cell (SOFC) is an all-solid-state chemical power generation device that converts chemical energy into electrical energy in an efficient and environmentally friendly way in medium- and high-temperature environments. However, the thermal stresses and creep damage are inevitably generated at high temperatures, which easily leads to ...

Deformation of the interconnect in a solid oxide fuel cell (SOFC) stack affects the internal thermal stresses of the cell at high temperatures. In this study, the effect of the interconnect deformation on the cell temperature and thermal stress at different operating voltages was simulated based on the thermal-chemical-electrical-mechanical multiph...

Numerical models are versatile tools to study and predict efficiently the performance of solid oxide cells (SOCs) according to their microstructure and composition. As the main contribution to the cell polarisation is due to the oxygen electrode, a large part of the proposed models has been focused on this electrode. Electrode modelling aims to imp...

Solid oxide fuel cells (SOFC) have gradually become possible to be used in the aviation field because of their high efficiency and fuel flexibility. The number of internal combustion engines (ICE) that are already in use is large, which makes it difficult to completely abandon them in a short period. Hence, finding low-carbon alternative fuels is s...
