recovery impedance
1.in O_2, the contribution of O_2 oxidizing MnOOH to the potential recovery of the compositeelectrode is very limited. The AC impedance analysis of MnO2-Pt/C composite electrode has disclosed: in the case of oxygen starvation with polarization potential of 0.3V vs.Ag/AgCl, the reaction resistances of Pt/C electrode and MnO2-Pt/C electrode is 196? and 3.04?
