      abstract     = {It is the aim of the present work to address some of the
                      aspects of microcracking in electron beam deposited
                      scandia-stabilised zirconia electrolyte applied for solid
                      oxide fuel cells (SOFC) where a thin electrolyte layer is
                      deposited on a relatively thick anode substrate. A model of
                      microcracking for the electrolyte material is proposed which
                      takes into account the statistical distribution of grain
                      sizes, the stress redistribution due to failure of
                      individual structural elements as well as the local
                      criterion of grain fracture. 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 annealing-induced electrolyte microcracking
                      discussed in this work corresponds to localised
                      microcracking, where each next structural element fails
                      mainly at an existing microcrack tip. The features of
                      localised microcracking in electron beam deposited
                      scandia-stabilised zirconia electrolyte are analysed. (C)
