| 摘 要： | 通过分析直接甲醇燃料电池(DMFC)的组成结构、工作原理，运用电化学、流体动力学、热力学等学科理论，建立DMFC电池性能数学模型，并根据DMFC实验数据进行了仿真。由于数学模型具有复杂性，难以满足工程上对DMFC控制系统的设计，特别是实时控制需要的情况，因此采用一种基于在线辨识的模糊预测算法对DMFC电堆进行建模。结果表明，这种数学建模是合理和可行的，对直接甲醇燃料电池控制系统的建模和控制具有一定的实用价值。

| Abstract: | The paper sets upa mathematical model of DMFC based on its structure and mechanism, using theories of electrochemistry, hydrokinetics and thermodynamics.And simulation is conducted according to the experimental data. The simulation results point to the validity and accuracy of the model.However this model is too complicated for controller design, especially for on-line controlling.So a fuzzy predictive algorithm based on on-line identification is presented for a family of complex system with severe nonlinearity such as DMFC. The results of simulation demonstrate the effectiveness of this approach,which is applicable for modelling and controlling of DMFC control system. |
