We reveal the positive influence of cyclic redox treatment (redox cycling) at 600°C on the strength and electric conductivity of anode substrates for ceramic fuel cells. As a result of this treatment of ceramic anodes of the 10Sc1CeSZ–50NiО and 8YSZ–50NiO systems, which includes the stages of heating up to a fixed temperature in a vacuum or in inert gases, reduction of the preheated material in hydrogen-containing atmospheres, degassing, and oxidation in air at the same temperature, we formed structures guaranteeing the improved physicomechanical properties (strength and electric conductivity) of these products.
