Small proportions (5 and 10 wt%) of strontium vanadate (Sr3(VO4)2) were added to strontium-doped lanthanum chromite (La0.85Sr0.15CrO3) to produce high density fuel cell interconnects in air at 1500C without adversely affecting the desirable properties of the material. Compositions investigated were shown to have good electrical conductivity at SOFC operating temperatures in air and reducing environments, phase stability from room temperature to 1000C, negligible thermal expansion mismatch with yttria-stabilized zirconia electrolytes and relatively low dilation at 10-16 atm.
