Redox Stable Anodes for Solid Oxide Fuel Cells
*Correspondence: Fanglin Chen, Department of Mechanical Engineering, University of South Carolina, 300 Main Street, Columbia, SC 29208, USA e-mail: [email protected] Solid oxide fuel cells (SOFCs) can convert chemical energy from the fuel directly to electrical energy with high efficiency and fuel flexibility. Ni-based cermets have been the most widely adopted anode for SOFCs. However, the conv...
متن کاملOperational Inhomogeneities in La0.9Sr0.1Ga0.8Mg0.2O3 Electrolytes and La0.8Sr0.2Cr0.82Ru0.18O3Ce0.9Gd0.1O2 Composite Anodes for Solid Oxide Fuel Cells
Ni cermet anodes are commonly used in solid oxide fuel cells (SOFCs) [1–4], but there has been considerable interest in alternative oxide-based anodes [5]. The motivation for the alternative materials is to avoid problems with the Ni-based anodes, including susceptibility to coking in hydrocarbon and CO-rich fuels [6], poisoning by sulfur [7] and other fuel impurities [8], and degradation due t...
متن کاملModel Development for Gadolinia- Doped Ceria-based Anodes in Solid Oxide Fuel Cells
Title of Document: MODEL DEVELOPMENT FOR GADOLINIADOPED CERIA-BASED ANODES IN SOLID OXIDE FUEL CELLS Lei Wang, Doctor of Philosophy, 2014 Directed By: Professor Gregory S. Jackson, Department of Mechanical Engineering Intermediate temperature (500 700 °C) solid oxide fuel cells (IT-SOFCs) with gadolinia-doped ceria (GDC) electrolytes have significant commercial potential due to reduced material...
متن کاملImportance of oxygen spillover for fuel oxidation on Ni/YSZ anodes in solid oxide fuel cells.
Using first principles simulations and the Monte Carlo method, the optimal structure of the triple-phase boundaries (TPB) of the Ni/Yttria-Stabilized Zirconia (YSZ) anode in solid oxide fuel cells (SOFCs) is determined. Based on the new TPB microstructures we reveal different reaction pathways for H2 and CO oxidation. In contrast to what was believed in previous theoretical studies, we find tha...
متن کاملBismuth oxide-based solid electrolytes for fuel cells
During the last three decades, a large number of investigations has been reported pertaining to the science and technology of solid oxide fuel cells (SOFCs) based mainly on the yttria-stabilized zirconia (YSZ) electrolyte. Because of the problems associated with the high temperature of operation ( ,-~ 1 000 ~ of the YSZ-based cells, there has been a substantial effort to develop alternative ele...
