As solid oxide fuel cell (SOFC) technology is rapidly evolving, high-fidelity mathematical models based on physical principles have become essential tools for SOFC system design and analysis. While several SOFC models have been developed by different groups using different modeling assumptions, little analysis of the effects of these assumptions on model performance can be found in literature. ...

Electrode materials which exhibit high conductivities in both oxidising and reducing atmospheres are in high demand for solid oxide fuel cells (SOFCs) and solid oxide electrolytic cells (SOECs). In this paper, we investigated Cu-doped SrFe0.9Nb0.1O3-δ finding that the primitive perovskite oxide SrFe0.8Cu0.1Nb0.1O3-δ (SFCN) exhibits a conductivity of 63 Scm(-1)and 60 Scm(-1) at 415 °C in air and...

BaZr0.8Y0.2O3-∂ (BZY)-NiO composite powders with different BZY-NiO weight ratios were prepared by a combustion method as anodes for proton-conducting solid oxide fuel cells (SOFCs). After heating to 1100°C for 6 h, the composite powders were made of a well-dispersed mixture of two phases, BZY and NiO. Chemical stability tests showed that the BZY-NiO anodic powders had good stability against CO2...

The changes in the surface phase and the morphology of nickel–yttria stabilized zirconia (YSZ) cermet anodes for solid oxide fuel cells (SOFCs) upon exposure to a fuel containing 100 parts per million (ppm)-level hydrogen sulfide (H2S) at elevated temperatures were investigated using in situ Raman microspectroscopy as well as ex situ techniques such as X-ray diffraction (XRD), scanning electron...

Abstract A solid oxide fuel cell (SOFC) with a liquid antimony anode (LAA) is potential energy conversion technology for the use of impurity-containing fuels. Atmospheric plasma spraying (APS) has become promising LAA-SOFC preparation method because its economy and convenience. In this paper, button SOFCs different cathode materials ratios pore former were prepared by APS operated at 750 °C. Th...

Solid oxide fuel cells (SOFCs) have been considered as promising candidates to tackle the need for sustainable and efficient energy conversion devices. However, current operating temperature of SOFCs poses critical challenges relating costs fabrication materials selection. To overcome these issues, many attempts made by SOFC research manufacturing communities lowering intermediate ranges (600–8...

As the pursuit towards emissions reduction intensifies with growing interest and nascent technologies, solid oxide fuel cells (SOFCs) remain an illustrious candidate for achieving our goals. Despite myriad advantages, SOFCs are still too costly for widespread deployment, even as unprecedented materials developments have recently emerged. This suggests that, in addition to informed materials sel...

Composites formed by infiltration of 45 wt % La0.8Sr0.2Cr0.5Mn0.5O3 (LSCM) into a 65% porous yttriastabilized zirconia (YSZ) scaffold were investigated in order to understand the reasons this material is able to provide excellent anode performance in solid oxide fuel cells (SOFCs). Scanning electron microscopy showed that the LSCM forms a film over the YSZ after calcination at 1473 K but that t...

Yttria stabilized zirconia (YSZ) has been widely used as electrolyte in solid oxide fuel cell (SOFC). The effect of fabrication process on the properties of YSZ electrolyte thick film is discussed in the paper. With YSZ nano-powders of about 20-60nm as raw material, YSZ green adobe was fabricated by tape calendering process. Three-step sintering process was performed firstly holding at 1000°C f...
