Sulfur tolerance of Ni/Gd2O3–CeO2 (Ni/GDC) anodes promoted by impregnated palladium nanoparticles is investigated using the electrochemical impedance spectroscopy (EIS) and galvanostatic polarization techniques in the H2–H2S fuels at 800 °C. The anodes are alternately polarized in pure H2 and H2S-co...
