Combustion Spray Process Leads to Rapid Fabrication of Porous SOFC Electrodes

The fabrication of porous electrodes with high surface area is of great importance for the development of efficient, low-temperature solid-oxide fuel cells (SOFCs). Recently, the focus has been on a combustion chemical vapor deposition (CVD) method that uses only soluble precursors, a relatively new technique that allows the fabrication of porous composite electrodes with nanostructural features and good electrochemical characteristics. Now, scientists at the Georgia Institute of Technology have invented a rapid combustion spray process using a suspension of solid powders with a particle size of less than 1 pm in a flammable solvent.
