The 18O/16O Isotope Exchange Depth Profile technique (IEDP) was applied to BIMEVOX.10 (ME=Cu, Co) materials to determine their oxygen exchange coefficients and bulk oxygen tracer diffusion coefficients. These results are compared to the exchange current densities obtained from current–voltage curves and bulk conductivity determined by impedance spectroscopy...
