Nucleation of nanometer-scale electrocatalyst particles in solid oxide fuel cell anodes
This letter describes a method for forming Ru nanoclusters on oxide anode surfaces during the initial stages of solid oxide fuel cell operation, ielding improved anode performance without additional processing steps. Transmission electron microscope and X-ray photoelectron spectroscopy ◦ bservations showed that Ru nanoclusters precipitated onto La0.8Sr0.2Cr0.82Ru0.18O3−δ surfaces after exposure...
متن کاملProton-conducting Micro-solid Oxide Fuel Cells with Improved Cathode Reactions by a Nanoscale Thin Film Gadolinium-doped Ceria Interlayer
An 8 nm-thick gadolinium-doped ceria (GDC) layer was inserted as a cathodic interlayer between the nanoscale proton-conducting yttrium-doped barium zirconate (BZY) electrolyte and the porous platinum cathode of a micro-solid oxide fuel cell (μ-SOFC), which has effectively improved the cathode reaction kinetics and rendered high cell power density. The addition of the GDC interlayer significantl...
متن کاملFabrication of low-temperature solid oxide fuel cells with a nanothin protective layer by atomic layer deposition
Anode aluminum oxide-supported thin-film fuel cells having a sub-500-nm-thick bilayered electrolyte comprising a gadolinium-doped ceria (GDC) layer and an yttria-stabilized zirconia (YSZ) layer were fabricated and electrochemically characterized in order to investigate the effect of the YSZ protective layer. The highly dense and thin YSZ layer acted as a blockage against electron and oxygen per...
متن کاملApplication of infiltrated LSCM-GDC oxide anode in direct carbon/coal fuel cells.
Hybrid direct carbon/coal fuel cells (HDCFCs) utilise an anode based upon a molten carbonate salt with an oxide conducting solid electrolyte for direct carbon/coal conversion. They can be fuelled by a wide range of carbon sources, and offer higher potential chemical to electrical energy conversion efficiency and have the potential to decrease CO2 emissions compared to coal-fired power plants. I...
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...
