abstract = {Mechanical reliability is one main prerequisite for the
long-term operation of Solid Oxide Fuel Cells (SOFCs) and
Solid Oxide Electrolysis Cells (SOEC) in stacks and systems.
Hence, key mechanical properties were derived for cells to
be used in Jülich stacks and systems. Since assembling and
joining is typically carried out in oxidized state, whereas
operation requires reduction of the anode, mechanical
characterizations are performed for cells in oxidized and
reduced state with additional consideration of elevated
temperature behavior as well as possible mechanical
degradation due to subcritical crack growth. In particular,
fracture strength, elastic modulus and residual stress for
half-cells were assessed. With respect to fracture strength,
also subcritical crack growth at different temperatures has
been analyzed, being the basis of a derived
strength-probability-time plot. Overall, the work provides
parameters for determination of failure probability and
lifetime prediction.},
