A modification of the phase inversion method that enables high-precision control of the geometric parameters (diameter, wall thickness, and degree of alignment) of anode microtubular substrates of solid oxide fuel cells was proposed. Due to unique properties of the phase inversion process, which occurs simultaneously with solvent melting, anode microtubes with increased porosity and gas permeability were obtained compared to the microtubes obtained by traditional phase inversion extrusion method.

The methodology for preparing precursors for the fabrication of the anode-supported tubular substrates from NiO/YSZ composite was developed. The optimal amount of the pore-forming agent to get the well-developed porosity in the supporting anode was determined. The relationship between the fabrication methods of the anodic and electrolytic functional layers in SOFCs was demonstrated.

To increase the specific characteristics of the surface electrodes, used in the lead accumulators it is necessary to exclude the influence of the internal stress in the paste which is obtained by the electrochemical way. One of the variants of the solutions of this problem is the electrochemical obtaining the paste under the pressure directed to the surface of the forming paste.
