A-site deficient La-doped SrTiO3 (La0.2Sr0.7TiO3) was evaluated as a potential anode component material for intermediate temperatures SOFCs. Button fuel cells were produced by tape casting and impregnation, comprising YSZ electrolyte, a porous, conductive backbone of La0.2Sr0.7TiO3 anode impregnated via solutions with Gd-doped CeO2 and a metal (i.e. Cu). Thin films of La0.6Sr0.4CoO3 cathode produced in-situ in the fuel cell test experiment. Fuel cells tests using pure, humidified H-2 as fuel demonstrated that remarkable power densities in excess of 0.5 W/cm(2) at 750 degrees C can be achieved with suitable pre-reduction of the titanate material.
