Single-chamber solid oxide fuel cells ~SOFCs! with an anode-supported Ce0.9Gd0.1O1.95 electrolyte were operated in a mixture of butane and air at furnace temperatures of 200-300°C. The electromotive force ~emf! of the cell and the voltage drop were strongly influenced by the catalytic activity of the anode for the partial oxidation of butane. The promotion of hydrogen formation by the addition ...

The effect of varying the CO-CO2 and CO2-N2 ratios was investigated in the presence of coal in a specially designed 3-electrode setup, used to simulate the anode compartment in a hybrid direct carbon fuel cell (HDCFC). The HDCFC consists of a hybrid between a molten carbonate and a solid oxide fuel cell (SOFC). It was shown that the cell performance improved with increased CO2 content in the CO...

Results show that Sm1.8Ce0.2CuO4 material is chemically compatible with Ce0.9Gd0.1O1.95 at 1000 °C. The composite electrode exhibits optimum microstructure and forms good contact with the electrolyte after sintering at 1000 °C for...

Ammonia represents one of the most promising potential solutions as energy vector and hydrogen carrier, having a higher to transport than itself in pressurized form. Furthermore, solid oxide fuel cells (SOFCs) can directly be fed with ammonia, thus allowing for immediate electrical power heat generation. This paper deals analysis dynamic behavior commercial SOFCs when fueled ammonia. Several me...

The mechanism whereby structural modification on the mesoscale order (10–100 ?m) improves electrochemical performance of anode-supported solid oxide fuel cells (SOFCs) is elucidated. After preparing two types SOFC having different electrode–electrolyte interfacial areas, we carry out their analyses and characterization. Next, develop a two-dimensional (2D) numerical model in which structures ar...

Fuel cells could play an important role in the ongoing energy transition by providing clean and efficient conversion. Although solid oxide fuel cell (SOFC) technology is a potential alternative for large-scale applications, its commercialization limited electrolyte materials has not yet been realized. Progress on new functional semiconductor-ionic (SIMs) fundamentals of SOFCs will provide paths...

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...

Abstract The Ce 0.8 Gd 0.2 O 2− δ (CGO) interlayer is commonly applied in solid oxide fuel cells (SOFCs) to prevent chemical reactions between the (La 1− x Sr )(Co y Fe )O 3− (LSCF) oxygen electrode and Y 2 3 -stabilized ZrO (YSZ) electrolyte. However, formation of YSZ–CGO solution with low ionic conductivity SrZrO (SZO) insulating phase still happens during cell production long-term operation,...
