摘要
燃料电池水热管理系统是维持燃料电池发动机水热平衡的核心系统,其流量、温度、压力分布等都对燃料电池发动机的性能、功耗和可靠性有着重要的影响.基于某额定功率120 kW的燃料电池发动机,从系统功能和性能最优的角度给出了架构方案设计、零部件选型匹配的理论依据,根据相关设计输入和设计目标要求,借助一维仿真软件FloMaster进行了水热管理系统的建模、仿真与结果分析,评估了系统在不同工况下流量、压力、温度和流速的分布,并通过台架试验手段进行了验证.仿真与试验结果表明,在系统额定工况和怠速工况点,水泵流量、电堆进出口温差、电堆入口温度等关键技术指标均满足系统目标需求.
Abstract
The water-thermal management system of a fuel cell is the core system that maintains the water-thermal balance of fuel cell engines.Factors such as flow rate,temperature and pressure distribution have significant impacts on the performance,power consumption,and reliability of fuel cell engines.Based on a 120 kW-rated fuel cell engine,a theoretical basis for architecture design and component selection matching was provided from the perspective of optimal system function and performance.According to relevant design inputs and objectives,the modeling,simulation,and result analysis of the water-thermal management system were carried out using the one-dimensional simulation software FloMaster.The distribution of flow rate,pressure,temperature,and velocity in the system under different operating conditions was evaluated,and verified through bench testing.The simulation and experimental results show that key technical indicators,such as the water pump flow rate,the temperature difference between the inlet and outlet of the fuel cell stack,and the inlet temperature of the fuel cell stack meet the system's target requirements under both rated and idle operating conditions.
