                      (PNCx) and Y-doped ceria Ce0.9Y0.1O2 − δ (YDC) oxideswere
                      synthesized via Pechini route. PNCx+YDC composites were
                      prepared via ultrasonic dispersion of the mixtureof
                      perovskite and fluorite nanopowders in isopropanol with
                      addition of polyvinyl butyral followed by drying,pressing
                      and sintering at 1300 °C. The oxygenmobility and reactivity
                      of powdered PNCx and composites obtainedby crushing and
                      milling of dense pellets were estimated by O2-TPD and oxygen
                      isotope exchange with 18O2 andC18O2 using both static and
                      flow (SSITKA) reactors in isothermal and
                      temperature-programmed (TPIE) modes.For PNCx samples
                      sintered at 1300 °C comprised of (Ni,Co)O and
                      Ruddlesden–Popper type phases (Pr2NiO4,Pr4(Ni,Co)3O10),
                      the oxygenmobility and reactivity tend to decrease with Co
                      content. For composites, the oxygenmobility ismuch higher
                      due to Pr transfer into YDC thus disordering perovskite-like
                      and fluorite-like phases. TPIEC18O2 SSITKA experiments
                      combined with SIMS analysis of the depth profiles of Pr18O
                      and Ce18O suggest thatfast oxygen diffusion in composites is
                      provided by domains of disordered perovskite-like phases as
                      well as Pr,Y-doped ceria. For best composites, the value of
                      the oxygen chemical diffusion coefficient estimated by
                      theweight relaxation technique exceeds that of well known
