Modelling of mechanical performances for planar sofc development

In the present work the thermo mechanical stability of planar is considered. For determination of the stable SOFC structures and prevention of complications during the operation a theoretical model of the deformation behavior was developed and solved. According to the results of the numerical interpretation of the received model a rational ratio of geometric relations of the planar SOFC design is determined. For classification of the planar SOFC deformation behavior and evaluation of the mechanical and reological properties of the SOFC electrode elements materials .on influence of different levels of operating temperatures the experimental studies are conducted. Experimental studies were conducted on a specially prepared and equipped installation with appropriate devices. Taking into account the capabilities of the experimental setup and the appropriate test targeting a program and methodics of experiments for conducting in conditions of high loads and operating temperatures is developed. Based on the methodology and in accordance with a program of experimental studies the mechanical behavior of materials proposed for the manufacture of electrode systems of developed SOFC designs in the form of charts and graphs are analyzed and presented.
