Open publisher page 2 citations

Abstract

A PEMFC stack simulation model was established by Matlab/Simulation software according to the characteristics of proton exchange membrane fuel cell (PEMFC) control system, such as nonlinear, time delay, complexity, and etc. The proportional integral differential (PID) algorithm controller was adopted to control the stack output current. The output voltage, output power and efficiency response of the stack were discussed when the output current had step changes, and the simulation results were compared. The simulation results show that the model can reflect the dynamic performance of PEMFC system, and the algorithm has a good robustness, which helps to improve the design of PEMFC control system and its performance.
