                      has great potential for the separation and purification of
                      hydrogen. However, due to the demanding application
                      conditions regarding both temperature and atmosphere, the
                      elevated temperature structural stability needs to be
                      characterized and warranted. Hence, in this research work,
                      the elevated temperature compressive creep behavior of
                      BaCe0.65Zr0.2Y0.15O3−δ in the temperature regime of
                      850°C to 1200°C was studied in both air and $4\%$ H2/Ar as
                      a function of the applied stress. The results indicate
                      different creep mechanisms depending on atmosphere and
                      temperature range. While dislocation creep was observed in
                      $4\%$ H2/Ar over the full range, a dislocation creep
                      mechanism was observed in air at temperatures ≤1050°C and
                      a diffusional creep mechanism at temperature ≥1100°C. A
                      detailed microstructural analysis of the post‐creep test
                      specimens revealed that the exposure to oxygen leads to
                      localized stoichiometric changes and a decomposition at the
                      surface.},
