Abstract
This paper constructs a dynamic mechanism model of the proton exchange membrance（PEM） electrolyzer from the perspectives of electrochemistry, thermodynamics, fluid dynamics, and electricity, describing the nonlinearity, dynamic characteristics, and coupling of internal multi-physical processes of PEM electrolyzer. Based on this, a method is proposed to split the ripple current into DC and AC components, aiming to more accurately reflect the impact of current ripple on hydrogen production efficiency. A hardware-in-the-loop simulation platform combining PEM electrolyzer and power electronic circuits is established, and ripple currents with different amplitudes and frequencies are tested. The hardware-in-the-loop simulation results are consistent with experimental data, verifying the accuracy of the model. This provides a theoretical basis and verification platform for studying the topology and control strategy of high-efficiency hydrogen production power converters.
