【Abstract】 Effective proton exchange membrane fuel cell(PEMFC)thermal management is one of the key factors that improve the reliability and durability of fuel cell batteries. This article controls the temperature of the electric stack by controlling the duty cycle of the fan. In the control method,the method for improving the PSO optimization fuzzy PID control; the temperature model that is finally built by Matlab/Simulink is simulated:the method can effectively solve the time-variables,large lag and uncertainty of PEMFC temperature control. A strong coupling problem makes a decrease of 57% relative to traditional PID control overdrawl,and the response time is shortened to 27.8%,and the response speed is fast,robust,and less than a small control effect.更多还原
