| Abstract: | Dry methane with various concentrations was directly entered the anode of the solid oxide fuel cells (SOFCs) of Ni-YSZ/YSZ/LSM（Ni-Y2O3 stabilized ZrO/YSZ/La0.85Sr0.15MnO3-δ）. The exhaust gases from anode were measured in-situ by gas chromatograph (GC) to study the reactions of dry methane under different current densities at the Ni-YSZ anodes. The reactions were determined by comprising the theoretical open-circuit voltage (OCV) to the measured one, analyzing quantitatively the exhaust gas and the activation energy of elementary reactions occurred to CH4 at the Ni-YSZ anodes. At 1000℃ oxidation of methane was found to take place in sequence from partial oxidation, CH4+2O2- → CO+H2O+H2+4e-， CH4+3O2- → CO+2H2O+6e- to complete oxidation with increasing current density at the Ni-YSZ anodes under 3.85% and 5.66% CH4 conditions. |
