Figure 5. Electrochemical impedance spectroscopy of R-PBMN anode measured at 650 °C under varying partial pressures of (A) H2 and (D) CH4. Corresponding distribution of relaxation times (DRT) analysis for (B) H2 and (E) CH4 atmosphere. Polarization resistance (Rp) dependence on (C) H2 and (F) CH4 partial pressures.
