      abstract     = {Iridium based particles as the most promising proton
                      exchange membrane electrolyser electrocatalysts were
                      investigatedby transmission electron microscopy (TEM), and
                      by coupling of electrochemical flow cell (EFC) with online
                      inductivelycoupled plasma mass spectrometer (ICP-MS).
                      Additionally, a thin-film rotating disc electrode (RDE), an
                      identical location transmissionand scanning electron
                      microscopy (IL-TEM and IL-SEM) as well as an X-ray
                      absorption spectroscopy (XAS) studies havebeen performed.
                      Extremely sensitive online time-and potential-resolved
                      electrochemical dissolution profiles revealed that
                      iridiumparticles dissolved already well below oxygen
                      evolution reaction (OER) potentials, presumably induced by
                      iridium surface oxidationand reduction processes, also
                      referred to as transient dissolution. Overall, thermally
                      prepared rutile type IrO2 particles (T-IrO2)are
                      substantially more stable and less active in comparison to
                      as prepared metallic (A-Ir) and electrochemically pretreated
                      (E-Ir)analogues. Interestingly, under OER relevant
                      conditions E-Ir particles exhibit superior stability and
                      activity owing to the alteredcorrosion mechanism where the
                      formation of unstable Ir(>IV) species is hindered. Due to
                      the enhanced and lasting OER performance,electrochemically
                      pre-oxidized E-Ir particles may be considered as the
                      electrocatalyst of choice for an improved low
                      temperatureelectrochemical hydrogen production device,
