Based on a solid oxide electrolyte, Ce_<0.8>Sm_<0.2>O_<1.9>, one chamber type methane-air fuel cells have been constructed. Fuel cells based on a Ce_<0.8>Sm_<0.2>O_<1.9> electrolyte gave current-voltage performances significant better than those of a comparable cell based on a perovskite solid electrolyte such as BaZr_<0.8>Y_<0.2>O_<2.9>. The performance of fuel cells were governed by the catalytic activity of the both electrode and the conductivity of the electrolyte.The fuel cells based on Ce_<0.8>Sm_<0.2>O_<1.9> electrolyte of 0.3 mm thickness generated 100 and 175 mA at a terminal voltage of 500 mV at temperatures of 700 and 750 ℃, respectively. In the methane-air fuel cell, the carbon deposition on the anode surface coming from the thermal decomposition of methane was serious problem. The coating of 1%Ru/Al_2O_3 catalysts coating on the anode component prevented the carbon deposition and maintained the stability of the methane-air fuel cell.

以固体氧化物电解质Ce_<0.8>Sm_<0.2>O_<1.9>为基础，构建了单室型甲烷-空气燃料电池。基于Ce_ Sm_ O_2电解质的燃料电池<0.8><0.2><1.9>的电流-电压性能明显优于基于钙钛矿固体电解质如BaZr_<0.8>Y_<0.2>O_2的燃料电池<2.9>。以0.3mm厚的CeSmO 2为电解质的燃料电池<0.8><0.2><1.9>，在700和750 ℃下，端电压为500 mV，输出电流分别为100和175 mA。在甲烷-空气燃料电池中，甲烷热分解产生的积碳是严重的问题。在阳极组件上涂覆1%Ru/Al_2O_3催化剂，可以防止积碳，保持甲烷-空气燃料电池的稳定性。
