Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | It is the aim of the present work to address some of the aspects of optimized technological approach of manufacturing planar anode-bearing solid oxide fuel cells based on detailed investigation of such effects as electrolyte microcracking and degradation, taking into account weakening of its grain boundaries due to impurity segregation during SOFC operation. The combination of electron microscopy research with model calculations permits both the specific energy of new surface creation in the electrolyte and critical parameters of the microcracking process to be determined. The accounting of segregation behavior features allows one to control electrolyte brittleness by using of optimal heat treatment regimes. |
