Abstract: 
The technological aspects of manufacturing planar solid oxide fuel cells (SOFC) with bearing anode on the basis of high conductive scandia-stabilized zirconia are considered. The results of our investigation of electron beam deposited scandia-stabilized zirconia-based electrolyte microcracking are presented. The topicality of such investigation is associated with the fact that electrolyte integrity is the prerequisite to reliability of SOFCs and their application in space vehicles. We discuss the mechanisms of SOFC component degradation via the decrease of their grain boundaries which is induced by impurity under operating conditions.
Keywords: electrolyte, electron beam, microcracking
