La1.5Nd0.3Pr0.2NiO4.16: A New Cathode Material for IT-Solid Oxide Fuel Cells
The La1.5Nd0.3Pr0.2NiO4.16 material was prepared by the citrate method and used as a cathode for a solid oxide fuel cell (SOFC). The study was carried out in the presence of a thin interfacial layer composed of 50% GDC10 and 50% 8YSZ deposited on both surfaces of the GDC10 (Ce1.9Gd0.1O1.95) electrolyte. The purity of the materials was studied by X-ray diffraction, while X-ray photon-electron spectrometry (XPS) was used to characterize the surface chemical state of the synthesized material; the morphology of the electrode and cross-sectional images of the cell were obtained by scanning electron microscopy (SEM). Iodometric titration has also been performed to evaluate oxygen over-stoichiometry. Cross-sectional SEM images have shown good adherence between all the cell components, and the cationic character of the cathode material was confirmed by the XPS and iodometric analysis. The use of these materials as an oxygen cathode has shown interesting electrochemical properties with an area-specific resistance (ASR) value of the order of 0.060 (Ω.cm2) at 600 °C and 0.022 (Ω.cm2) at 700 °C. The activation energy (Ea) of the LNPNO5 material is very low and is of the order of 0.96 eV.

2. At 600 and 700 °C, the ASRs of La1.5Nd0.3Pr0.2NiO4.16 were as low as 0.06 Ω.cm2 and 0.022 Ω.cm2, respectively.
3. The presence of the new interfacial layer (8YSZ (50%) + GDC10 (50%) is of interest to operate at intermediate temperatures for SOFCs.
4. La1.5Nd0.3Pr0.2NiO4.16 can be qualified to be an excellent cathode material for SOFC fuel cells operating at intermediate temperatures, 600 – 700 °C.
