.... The as-proposed impregnation route avoided the conventional fabrication problem for the Ag based electrode due to the low melting point of Ag (ca. 962 ° C ), and allowed the Ag nanoparticles to infiltrate into the established cathode with a very homogeneous distribution and a good adhesion to the ceramic...

... was examined in the temperature range 850 – 650 ° C . The cell performance was improved by infiltrating the nanoparticle Bi 2 O 3 – Eu 2 O 3 solid solution into the porous LSM-YSZ cathode. The power density of the cell with the LSM-LSZ cathode was enhanced from 0.28 W / cm 2 to 0.52 W / cm 2 at 0.7 V and 750...
