A new challenge in the field of solid oxide fuel cells (SOFCs) concerns reducing their operating temperature to 973 K. Apatite ceramics are interesting candidates for SOFC electrolytes due to their high ionic conductivity at this temperature. The present work reports on the fabrication and character
Scheelite-type, La x Ca 1-x MoO 4+ฤฑ electrolyte powders, are prepared by the sol-gel process. The crystal structure of the samples is determined by employing the technique of X-ray diffraction (XRD). According to XRD analysis, the continuous series of La x Ca 1-x MoO 4+ฤฑ (0 โค x โค 0.3) solid solution
## Abstract Many new materials have been identified as being of potential interest to solid oxide fuel cell developers. Recent work has suggested that materials of the La~2~NiO~4~ composition possess sufficient activity to act as an effective cathode. Whilst there have been many studies of the tran
