Abstract
The effect of introducing 1–3 wt % copper oxide sintering additive on the electrical and electrochemical characteristics of promising anode materials for solid oxide fuel cells based on Sr2Fe1.5Mo0.5O6–δ was studied. The total conductivity increases with increasing amount of copper oxide. The maximum conductivity in humid hydrogen at 800°C, 45 S cm–1, was reached on introducing 3 wt % CuO. The sintering additive enhances the electrochemical activity of Sr2Fe1.5Mo0.5O6–δ and Sr2Fe1.5Mo0.5O6–δCe0.8Sm0.2O1.9 anodes. A decrease in the sintering temperature of the anodes containing CuO with the electrolyte based on lanthanum gallate directly correlates with the electrochemical activity of the anodes. The minimum value of the polarization resistivity, 0.15 Ω cm2 at 800°С in a humid hydrogen atmosphere, was obtained for the composite anode with 3 wt % CuO sintered at a temperature of 1050°С.
