摘　　要：以8％molY2O3稳定的ZrO2（8YSZ）为电解质、Ni-8YSZ为阳极，研究了不同电流密度、甲烷浓度和反应温度下，甲烷在固体氧化物燃料电池（SOFC）中由部分氧化到完全氧化转变的规律。在1000℃下、甲烷浓度为4．2％时，由部分氧化转变为完全氧化的临界电流密度为0．384-0．512A／cm^2，该值与甲烷浓度及温度成正比。The rules of methane from partial oxidation to complete oxidation in solid oxide fuel cell （SOFC） under different current density, methane concentration and temperature were studied with 8 % mol Y2O3 stabilized ZrO2 （8YSZ） as electrolyte and Ni-8YSZ as anode. The critical current density of partial oxidation transferred to complete oxidation was 0.384 - 0.512 A/cm^2 at 1 000 ℃ when methane concentration was 4.2%. The value was in the direct ratio to the methane concentration and temperature.
