摘　　要：利用燃料电池技术研制出的传感器可以定量检测微量可燃气体的种类和含量,预测它们的变化趋势。讲述了固体氧化物燃料电池的工作原理,从电荷守恒、动量守恒、能量守恒和组分守恒等定律出发,建立了管式固体氧化物燃料电池的数学模型。通过迭代法求解微分方程,以H2,CO,和CH4为研究对象,得到可燃气体的含量与由基准电压和输出电压组成的峰面积函数曲线。计算结果表明曲线在一定范围内呈现出线性特征。Gases types, content and development can be measured by the fuel ceil （FC） sensor. Basic principle of FC was introduced. Mathematical model of tubular SOFC was established according to 4 conservation laws, conversation of charge, energy, momentum and components. The differential equations were calculated by iterative method, and function image between output peak areas and contents of 3 kinds of combustible gas, such as H2, CO and CH4. The result shows that curve is linear in fixed scope.
