Performance of Ceria-electrolyte Solid Oxide Fuel Cell Using Simulated Biogas Mixtures as Fuel
In this study, a samarium cerium electrolyte-supported solid oxide fuel cell (SOFC) was assembled with Ce0.8Sm0.2O2−δ (SDC) electrolyte, La0.58Sr0.4Fe0.8Co0.2O3-δ (LSCF) as cathode and WNi-Ce as anode. A porous layer of SDC between anode and electrolyte was used to improve adhesion of the anode ink. The cell performance was investigated with hydrogen and three simulated biogas mixtures (CH4/CO2...
متن کاملSimulation of a Solid Oxide Fuel Cell with External Steam Methane Reforming and Bypass
Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
متن کاملRaman spectroscopy as a probe of temperature and oxidation state for gadolinium-doped ceria used in solid oxide fuel cells.
Raman spectroscopy is a noninvasive and highly sensitive analytical technique capable of identifying chemical compounds in environments that can mimic SOFC operating conditions. Here we demonstrate the use of Raman spectroscopy to perform local thermal and temporal measurements, both of which are essential if phase formation diagrams are to be mapped out and compared to thermodynamic phase stab...
متن کاملStudy of ceria-carbonate nanocomposite electrolytes for low-temperature solid oxide fuel cells.
Composite and nanocomposite samarium doped ceria-carbonates powders were prepared by solid-state reaction, citric acid-nitrate combustion and modified nanocomposite approaches and used as electrolytes for low temperature solid oxide fuel cells. X-ray Diffraction, Scanning Electron Microscope, low-temperature Nitrogen Adsorption/desorption Experiments, Electrochemical Impedance Spectroscopy and ...
متن کاملThermodynamic Stability of Gadolinia-Doped Ceria Thin Film Electrolytes for Micro-Solid Oxide Fuel Cells
Next-generation micro-solid oxide fuel cells for portable devices require nanocrystalline thin-film electrolytes in order to allow fuel cell fabrication on chips at a low operation temperature and with high power outputs. In this study, nanocrystalline gadolinia-doped ceria (Ce0.8Gd0.2O1.9!x) thin-film electrolytes are fabricated and their electrical conductivity and thermodynamic stability are...
