基于固态储氢与燃料电池耦合的车载氢能源系统建模与特性分析
Modeling and Performance Evaluation of the MH-PEM Hydrogen Power System for Vehicle Use
摘要
Abstract
The performance of the hydrogen power system is a critical factor in the design of fuel cell electric vehicles,as it includes the device's characteristics,control effectiveness,and energy management outcomes.This study investigated a typical hydrogen power system that uses a metal hydride(MH)hydrogen storage tank and a proton exchange membrane(PEM)fuel cell.The aim was to evaluate the thermal coupling effects of the MH-PEM hydrogen power system through mathematical modeling and real-world traffic testing.First,a multi-physical field coupling model of the MH-PEM hydrogen power system was proposed based on the structure of the thermal exchange system.Then,numerical simulations and experiments were conducted based on the operating conditions of a range-extended fuel cell hybrid electric vehicle.The results indicated that the proposed mathematical model can accurately characterize the dynamic features of the onboard hydrogen energy system.The comparison of simulation and experimental results showed great agreement,particularly in terms of power response and temperature dynamics.Further analysis of the influence of atmospheric temperature on the hydrogen supply flow was carried out by examining the temperature variation in the MH tank.The results show that the thermal coupling design is an effective method for improving energy efficiency.The results of this study may be used for optimal sizing,temperature control,and energy management strategy design of MH-PEM hydrogen power systems.关键词
