    Project RFBR No. 19-38-90194
    Investigations of influence of anode supports microstructure on electrochemical characteristics of anode-supported SOFCs.


    In this work, a manufacturing technology was developed for production of a two-layer (current-collecting and functional layers) substrate for planar anode-supporting SOFCs: the relationship between the mechanical characteristics and the microstructure of the anode substrates depending on the type and concentration of the porous agent and the parameters of the suspension was studied. As a result, the optimal porosity in the collector layer, the optimal amount of organic components in the suspensions of the collector and functional layers were determined, a high-temperature processing was developed to avoid bending deformations in a two-layer structure.
    We studied the possibility of forming a thin gas-tight electrolyte layer on a sintered supporting substrate from an ablative, weakly agglomerated, and highly agglomerated 8YSZ powder made by screen printing technology. It was shown that a temperature of 1300°C is not enough for the formation of a dense structure due to the low initial density, which is due to the high concentration of solvent in the paste. Thus, a decision was to increase the annealing temperature up to 1600 °C. Electrochemical tests will be carried out after obtaining a gas-tight electrolyte layer at elevated temperatures.
