After its one-time reduction in the presence of carbon dioxide in a hydrogen-containing environment (N2–10%H2–5%CO2), strength of 8YSZ–Ni cermet decreases by 15% compared to that reduced in Ar–5%Н2 mixture. This is due to the deposition of carbon at the ZrO2–Ni interphases. Technological modes for production of ceramics of 50% (ZrO2 – 8 mol%Y2O3 – 2 wt% Al2O3) + 50% (NiO – 5 wt% CuO) composition were optimized in terms of the temperatures of calcination of powders (700°С) and their sintering (1400°С), which allowed to obtain a fine-grained microstructure and increased both strength and electrical conductivity of the corresponding cermet. After reduction in N2–10%H2–5%CO2 gas mixture, the cermet does not lose its mechanical properties compared to the as-sintered ceramics. This ceramic is promising as anode material for a SOFC operating, for example, on syngas. High oxidation resistance and electrical conductivity in high-temperature (600℃) oxidizing medium is demonstrated by the coating of the Ti–Al–C system, applied by arc –plasma method on a thin (0.5 mm) titanium plate of the VT1-0 brand. This is due to the formation of oxidation-resistant and electrically conductive phases of Ti3AlC (with antiperovskite crystal structure) and TiAl and Ti3Al. On this basis, you can create light interconnections SOFC as an alternative to those used from steel type Crofer, which will significantly (~ 50%) reduce the weight of batteries SOFC.
