      abstract     = {Re-oxidation robustness is important to warrant a reliable
                      operation of anode-supported solid oxide fuel cell systems.
                      The current work concentrates on the mechanical properties
                      of re-oxidation stable Y-substituted SrTiO3 ceramic for the
                      use as anode substrate material. Room temperature
                      micro-indentation yielded Young's modulus and hardness of
                      160 and 7 GPa, respectively, whereas the
                      temperature-dependent modulus was measured with a
                      resonance-based method up to ∼950 °C. The effective
                      Young's modulus as a function of porosity was measured at
                      room temperature and compared with fracture strength data.
                      The fracture toughness was assessed using a combination of
                      pre-indentation cracks and bending test. Creep rates were
                      measured at 800 and 900 °C in a 3-point bending
                      configuration. Post-test fractographic analysis performed
                      using stereo, confocal and scanning electron microscopy,
                      revealed important information on fracture origins and
                      critical defects in the material. A methodology to assess
                      the mechanical properties of porous materials is suggested.},
