      abstract     = {Advanced oxygen transport membrane designs consist of a
                      thin functional layer supported by a porous substrate
                      material that carries mechanical loads. Creep deformation
                      behavior is to be assessed to warrant a long-term reliable
                      operation at elevated temperatures. Aiming towards an
                      asymmetric composite, the current study reports and compares
                      the creep behavior of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF)
                      perovskite porous substrate material with different porosity
                      and pore structures in air for a temperature range of
                      800–1000 °C. A porosity and pore structure independent
                      average stress exponent and activation energy are derived
                      from the deformation data, both being representative for the
                      LSCF material. To investigate the structural stability of
                      the dense layer in an asymmetric membrane, sandwich samples
                      of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) and
                      La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) with porous substrate and
                      dense layers on both side were tested by three-point bending
                      with respect to creep rupture behavior of the dense layer.
                      Creep rupture cracks were observed in the tensile surface of
                      BSCF, but not in the case of LSCF.},
