摘要
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.关键词
