In the context of the national dual-carbon policy,solid oxide fuel cell power generation has become one of the current environmentally friendly and efficient power generation methods. In the process of-power generation,the parameter setting and selection of the chemical reaction controller has become one of the key issues in scientific research. In this paper,a variable gain PID regulator is proposed,a mathematical model of mass balance system is established,the parameters of the chemical reaction controller of the power generation process of solid oxide fuel cell are designed and selected,and the Simlink controlin MATLAB is used for system simulation,and the simulation results show that the system and parameter settings designed in this paper can effectively control the p H value of the chemical reaction in the power-generation process,so that the power generation voltage and current output can be further optimized.
