To stabilize solid oxide fuel cells cathodes prepared by infiltration of La0.8Sr0.2CoO3 (LSCo) into porous yttria-stabilized zirconia (YSZ), a coating of Sm-doped ceria (SDC) was first deposited onto the YSZ scaffold. The dense SDC coating was prepared by infiltration with aqueous solutions of SM(NO3)3 and Ce(NO3)3, followed by calcination to 1473 K. The SDC coating prevented ~ 20 mΩ cm2, at 973 K, with acceptable degradation after heating to 1373 K.
