Figure 6. (A) Thermogravimetric analysis (TGA) of R-PBM and R-PBMN from room temperature to 1,000 °C. (B) TGA profiles after treatment in wet air (30 vol% H₂O) at 650 °C for 3 h. (C) CH₄-temperature programmed desorption (TPD) profiles. (D) H₂-temperature programmed reduction (TPR) profiles. (E) Area-specific resistance (R_p) stability of symmetrical cells with R-PBM and R-PBMN electrodes at 650 °C in steam methane reforming (S/C = 1:2) for 120 h. (F) Raman spectra of R-PBM, R-PBMN, and reference Ni catalyst after steam methane reforming (S/C = 1:2) at 650 °C for 24 h.
