Study of Praseodymium Strontium Manganite for the Potential use as a Solid Oxide Fuel Cell Cathode: Author: Pfluge, Matthew Edward; Date: 2005-05-15; Program: Chemical Engineering; Abstract: Extensive research has been performed on solid oxide fuel cell cathodes. These cathodes must be stable in the oxidation environment and have sufficient electrical conductivity and catalytic activity for the oxidant gas reaction at the appropriate operating temperature. Also, the cathode must be chemically and thermally compatible with the other cell components at room temperature, operating temperatures, and higher fabrication temperatures. Praseodymium strontium manganite (PSM) has shown promising electrical properties with respect to ideal properties of cathodes in solid oxide fuel cells. Va...; Download File | View full details

Study of Solid Oxide Fuel Cell Interconnects, Protective Coatings and Advanced Physical Vapor Deposition Techniques: Author: Gannon, Paul Edward; Date: 2007-05-15; Program: Engineering; Abstract: High energy conversion efficiency, decreased environmentally-sensitive emissions and fuel flexibility have attracted increasing attention toward solid oxide fuel cell (SOFC) systems for stationary, transportation and portable power generation. Critical durability and cost issues, however, continue to impede wide-spread deployment. Many intermediate temperature (600-800°C) planar SOFC systems employ metallic alloy interconnect components, which physically connect individual fuel cells into electric series, facilitate gas distribution to appropriate SOFC electrode chambers (fuel/anode...; Download File | View full details
