Abstract

The multilayered cathodes of nanoporous microstructure for SOFCs were developed using a polymeric resin as a nanoscale pore former that was prepared by a modified Pechini method. An LSM-YSZ composite layer was placed on the interface between electrode/electrolyte as a reaction active layer, then LSCF as a current collector was deposited by screen printing. Adding the polymeric resin component to the particulate paste permits us to produce a nanoporous electrode with high porosity and large surface area after heat treatment. The pore structure of a composite cathode is a function of the polymeric resin added in the paste. The electrochemical cell of this microstructural feature showed significantly improved electrocatalytic activity toward oxygen reduction. Microstructural evolution and the performance of the electrochemical cells with multilayered cathodes were investigated by SEM and impedance spectroscopy.
