abstract = {Solid oxide fuel cells (SOFCs) provide electrical energy
through a highly efficient direct transformation of chemical
energy stored in fuels. The sealing between the stacked
components of the SOFC has to prevent gas leakage towards
the environment as well as mixing of fuel gas and oxidant in
order to ensure a reliable long-term operability. Hence, the
understanding of the sealing loading conditions and the
failure assessment plays a major role regarding the
improvement of current and future SOFC designs. In the
present study, glass ceramics sealing failure is
investigated by means of a current SOFC design. For this
purpose, the stresses in the sealings are firstly examined
by employing a fully parameterized three-dimensional finite
element model. On the basis of a canonical example, the
underlying physical mechanisms, which are responsible for
the occurrence of stresses, are identified and their
influence is discussed. Since the initiation of sealing
failure is complex and depends on several parameters, a
methodology for failure assessment is proposed. In this
context, the glass transition temperature is of
superordinate importance. Since the material properties
differ significantly depending on whether the operating
temperature is below or above the glass transition
temperature, several competing failure mechanisms must be
considered.},
