Bismuth 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...
متن کاملStudy on Zinc Oxide-Based Electrolytes in Low-Temperature Solid Oxide Fuel Cells
Semiconducting-ionic conductors have been recently described as excellent electrolyte membranes for low-temperature operation solid oxide fuel cells (LT-SOFCs). In the present work, two new functional materials based on zinc oxide (ZnO)-a legacy material in semiconductors but exceptionally novel to solid state ionics-are developed as membranes in SOFCs for the first time. The proposed ZnO and Z...
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 کاملImproved solid oxide fuel cell performance with nanostructured electrolytes.
Considerable attention has been focused on solid oxide fuel cells (SOFCs) due to their potential for providing clean and reliable electric power. However, the high operating temperatures of current SOFCs limit their adoption in mobile applications. To lower the SOFC operating temperature, we fabricated a corrugated thin-film electrolyte membrane by nanosphere lithography and atomic layer deposi...
متن کاملA New Sensitivity Study of Thermal Stress Distribution for a Planar Solid Oxide Fuel Cell
Converting chemical energy into electricity is done by an electro-chemical device known as a fuel cell. Thermal stress is caused at high operating temperature between 700 oC to 1000 oC of SOFC. Thermal stress causes gas escape, structure variability, crack initiation, crack propagation, and cease operation of the SOFC before its lifetime. The aim of this study is to presen...
