【Abstract】 The article focused on the mathematical simulation model of the dynamic performance of proton exchange membrane fuel cells under low hydrogen pressure conditions. Different from the traditional method of building reactor modules, we built a PEMFC stack model based on the Thermolib full-parameterized fuel cell simulation model library under the MATLAB/Simulink environment. The performance of reactor output voltage, which is varied with hydrogen and oxygen supply pressure,flow rate, and battery operating temperature, was discussed. The simulation results show that the output characteristics and dynamic response of the fuel cell under low hydrogen pressure conditions are well simulated, and the voltammetry curves are in good agreement with the experimental data, which reflects that the reliability, operability and effectiveness of the established model. This study also lays a good foundation for the subsequent establishment of fuel cell system model and understanding of its dynamic behavior.更多还原
