      abstract     = {The oxygen evolution reaction (OER) during alkaline water
                      electrolysis is the bottleneck of water splitting.
                      Perovskite materials have been particularly proposed as good
                      and economically reasonable electrocatalysts for the OER,
                      showing promise and advantages with respect to classic
                      metallic electrodes. However, the degradation of perovskites
                      during catalysis limits their service lifetime. Recently,
                      the material BaCo0.98Ti0.02O3−δ:Co3O4 was shown to be
                      electrocatalytically and chemically stable during water
                      electrolysis even under industrially relevant conditions.
                      The lifetime of this perovskite-based system is prolonged by
                      a factor of 10 in comparison to that of Pr0.2Ba0.8CoO3−δ
                      and is comparable to that of industrially applied
                      electrodes. Here we report on the degradation kinetics of
                      several OER catalysts at room temperature, comparatively
                      studied by monitoring the oxygen evolution at
                      microelectrodes. A decrease in the reaction rate within a
                      maximum of 60 s is observed, which is related to chemical
                      and/or structural changes at the oxide surface.},
