The Effect of the Pore Former Nature on the Microstructure of Solid-Oxide-Fuel-Cell NiO- and 10YSZ-Based Anodes Formed by Hybrid 3D-Printing

The anodes based on the nickel oxide and yttria-stabilized zirconia are developed by the method of hybrid inkjet 3D-printing with laser treatment. The granulometric composition of the NiO/Zr_0.9Y_0.1O₂-composite and the rheological characteristics of its based printing pastes are determined. The printing of three-dimensional test objects using the developed ceramic paste is studied experimentally. The influence of the pore formers—graphite and potato starch—added to the paste composition on the rheological characteristics of the paste is studied. The obtained samples of supporting anodes were studied by a complex of physicochemical methods to determine their morphological and structural characteristics.
