SOFC建模与控制策略的研究现状与发展

简单介绍了固体氧化物燃料电池(SOFC)的单体结构类型和工作原理;然后详细介绍SOFC的电极、单电池、电堆、系统四个层次的建模以及SOFC控制的研究现状,并指出现有模型的不足;接着讨论SOFC电池数学建模的发展方向;最后,针对SOFC系统的非线性、大时滞、多输入多输出和随机干扰等特征,提出了几种适宜的控制方案.

Research status and development of modeling and controlling for SOFC

The configurations and the principles of solid oxide fuel cell (SOFC) were introduced simply. The present status of SOFC modeling for electrode, single cell, stack and system levels and the development of its control design were expounded, and the drawbacks of the present models were given also. And then, the future development trend of SOFC mathematical modeling was discussed. In the end, according to the nonlinear, time-delay, multivariable stochastic disturbance characters of SOFC, several suitable control strategies were presented.
