摘要
仿真技术是研究固体氧化物燃料电池并加快其商业化开发周期的重要方法之一。基于固体氧化物燃料电池的基本原理,即综合考虑电池内部的质量平衡、能量平衡和电化学反应过程,运用Matlab/Simulink建立了固体氧化物燃料电池的集总模型。运用此模型仿真了当负载发生变化时,电池的温度和输出功率的动态响应情况。并对单电池模型引入了基于电流的控制策略,用以保证在负载发生变化时单电池的安全运行。仿真结果表明此类简单的控制策略并不能保证电池的正常工作温度和良好的负载追随性,因此在商业化开发类似控制系统时,必须对系统加以更为完善的控制。
Simulation technology is an important method to study the solid oxide fuel cell and accelerate its development cycle.In the paper,a dumped model of the solid oxide fuel cell was established using the Matlab/Simulink software,based on the basic principles of the solid oxide fuel cell,namely,comprehensive consideration of the mass balance,energy balance,and the electrochemical reaction process in the fuel cell.The dynamic response of the temperature and output power of the cell was simulated using this model when the load changed.A current-based-fuel-control strategy was used in the simulation to ensure the safe operation of the fuel cell.The simulation results show that such a simple control strategy cannot guarantee the normal working temperature and a good load-following capacity of the fuel cell.Therefore,for the commercial development of a similar control system,a more consummate control strategy is needed.
