摘要：

Lowering the working temperature of solid oxide fuel cells (SOFCs) is the main trend in their development, which requires selection of materials for electrolyte and electrodes. A highly conducting lanthanum gallate-based electrolyte is a promising material for creating medium-temperature SOFCs. The electrochemical characteristics of the La0.6Sr0.4Fe0.8Co0.2O3 - delta cathode that contacted with the La0.88Sr0.12Ga0.82Mg0.18O2.85 electrolyte subject to electrode formation temperatures have been investigated. It was found that at optimum bake-on temperatures of 1200-1250A degrees C, the cathode polarization resistance at 800A degrees C was similar to 0.08 Ohm cm(2), which is comparable to the world's best achievements.
