Improved 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 approach to microstructure optimization of solid oxide fuel cell electrodes
Designing optimal microstructures for solid oxide fuel cell (SOFC) electrodes is complicated due to the multitude of electro-chemo-physical phenomena taking place simultaneously that directly affect working conditions of a SOFC electrode and its performance. In this study, a new design paradigm is presented to obtain a balance between electrochemical sites in the form of triple phase boundary (...
متن کاملAn octane-fueled solid oxide fuel cell.
There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...
متن کاملIntegrating Multiple Solid Oxide Fuel Cell Modules
Abstract-According to SECA program guidelines, solid oxide fuel cells (SOFC) will be produced in the form of 3–10 kW modules for residential use. In addition to residential use, these modules can also be used in apartment buildings, hospitals, etc., where a higher power rating would be required. For example, a hospital might require a 250 kW power supply. To provide this power using the SOFC mo...
متن کاملIn Situ X-ray and Electrochemical Studies of Solid Oxide Fuel Cell / Electrolyzer Oxygen Electrodes
The governing reaction mechanisms, and the electrode material compositions and structures, that controls the efficiency of the solid oxide fuel cells (SOFC) and solid oxide electrolysis cells (SOEC) need to be identified and well-understood for significant technological improvements. Our study on the oxygen electrodes focuses on specifically the effect of electrode crystal structure and morphol...
