      abstract     = {Ce0.8Gd0.2O2−δ‐FeCo2O4 composites are attractive
                      candidate materials for high‐purity oxygen generation
                      providing robust chemical stability. Aiming for future
                      industrial applications, a feasible solid‐state reaction
                      process with one thermal processing step was used to
                      synthesize 50 $wt\%$ Ce0.8Gd0.2O2−δ:50 $wt\%$ FeCo2O4 and
                      85 $wt\%$ Ce0.8Gd0.2O2−δ:15 $wt\%$ FeCo2O4 composites.
                      Mechanical reliabilities of the sintered membranes were
                      assessed based on the characterized mechanical properties
                      and subcritical crack growth behavior. In general, the
                      fracture strengths of as‐sintered membranes were reduced
                      by tensile residual stresses and microcracks. In particular,
                      the enhanced subcritical crack growth behavior, which leads
                      to limited stress tolerance and high failure probability
                      after a 10‐year operation, was evaluated in more detail.
                      Further materials and processing improvements are needed to
                      eliminate the tensile stress and microcracks to warrant a
                      long‐term reliable operation of the composites.},
