… The activation energies for thermal reduction of Ce_<0.8>Zr_<0.2>O_2 were evaluated to be 102 kJ/mol. … This value was higher than the activation energies for ion conductivities of Ce_<0.8>Zr_<0.2>O_2, which suggests that the rate-determining step of the O_2 releasing reaction is the oxygen molecule formation step from the lattice oxygen ions of the ceramics. …
