| Abstract: | The reactions of low and middle concentration dry methane were studied over the anode of solid oxide fuel cell(SOFC) with Ni/yttria-stabilized zirconia(YSZ) anode and YSZ electrolyte.The production rates of different gases at anode outlet were measured at different current density values.Mass balance and the relation of production rate with reaction rate were used to analyze the chemical and electrochemical reactions taking place in parallel.For low concentration dry methane,partial oxidation of methane occurred at low current density,while electrochemical oxidations of hydrogen and carbon monoxide took place at increased current density.For middle concentration methane,only partial oxidation of methane occurred.Carbon deposition was found in all the tests. |
