Fabrication of solid oxide cell components and their electrochemical characterization

At GTU, we fabricate solid oxide cell (SOC) components (i.e., electrodes and electrolytes) using both conventional and novel techniques. We use single liquid precursors to fabricate both monophase and composite electrodes via self assembly of electrocatalyst and ionic conductor phases (see references 1 and 2 below for the composite electrode fabrication). We also fabricate single phase or composite electrolytes by infiltration-aided sintering (Refs 3 and 4).

In general, we are also interested in finding out the mechanisms through which SOC electrodes degrade and developing methods to mitigate them (Refs 5 and 6). We frequently use electrochemical impedance spectroscopy and potentiometry for the electrochemical characterization of the SOC components we develop.
