Study Results from Korea Institute of Materials Science Provide New Insights into Alloys and Compounds

By a News Reporter-Staff News Editor at Journal of Technology -- Researchers detail new data in Alloys and Compounds. According to news reporting originating in Chang Won, South Korea, by VerticalNews journalists, research stated, "Nano-structured porous similar to 20 mu m thick LSCF films were fabricated at room temperature for use as cathodes in low temperature operating solid oxide fuel cells. Fabrication was by the aerosol deposition of ceramic-polymer composite powder."

The news reporters obtained a quote from the research from the Korea Institute of Materials Science, "Various amounts of pore forming polyvinylidene fluoride polymer powder were mixed with LSCF ceramic powder as the starting powder for aerosol deposition. Increasing polymer content increased the porosity of films and decreased their adhesion strength. Anode-supported-type cells were created with LSGM electrolyte and nano-structured LSCF cathodes."

According to the news reporters, the research concluded: "The cells' power density was maximized at 0.79 and 1.11 W/cm(2) at 650 and 750 degrees C, respectively, when the starting composite powder contained 5 wt.% polymer."
