摘要:
为了研究热管理系统操作参数对质子交换膜燃料电池冷却效果的影响, 基于 MATLAB / Simu- link 仿真平台建立了燃料电池热管理系统的动态模型并对模型的正确性进行了验证,该系统模型包括电堆电压、温度模型和冷却回路模型;以建立的系统模型为研究基础,以冷却系统中旁路阀开度、冷却液 流量、空气流量 3 个操作参数为独立变量,研究冷却液入口温度、出口温度和出入口温差随独立变量的变化规律和影响情况。 研究结果表明,空气流量对冷却液入口温度和出口温度影响最大,当空气流量从最小值增加到最大值的过程中,冷却液入口温度和出口温度分别随之下降 27. 9 ~ 29. 0 ℃ 、26. 6 ~ 28. 4 ℃ ;旁路阀开度和冷却液流量在一定范围内对冷却液入口温度和出口温度都有影响,前者的影响强于后者,旁 路阀开度在小于 0. 7 时影响作用更显著;冷却液流量对冷却液出、入口温度的影响最小,对冷却液出入口温差的影响最大,当冷却液流量从最小值增到最大值的过程中冷却液出入口温差下降约 9 ℃ 。
Abstract:
In order to study the influence of the operating parameter of thermal management system on the cooling effect of proton exchange membrane fuel cell ( PEMFC), a dynamic model of the PEMFC thermal management system was established based on the MATLAB / Simulink simulation platform and the correctness of the system model was verified. The model included voltage model and temperature model of stack and cool- ing circuit model. Bypass valve opening, coolant flow, and air flow were regarded as independent variables and the change rule and influence of independent variables on coolant temperature at inlet and outlet and cool- ant temperature difference between inlet and outlet were studied through established system model. The results showed that when the air flow increased from the minimum to the maximum, the air flow had the greatest im- pact on the coolant temperature at inlet and outlet which droped by 27. 9 - 29. 0 ℃ and 26. 6 - 28. 4 ℃ , respectively. Both bypass valve opening and coolant flow had an effect on the coolant temperature at inlet and outlet, meanwhile the former had a stronger effect than the latter and the effect of bypass valve opening was more prominent when it less than 0. 7. Although the coolant flow had the smallest influence on the temperature of the coolant inlet and outlet, it had a dominant effect on the coolant temperature difference between the cool- ant inlet and outlet which droped by about 9 ℃ when the air flow increased from the minimum to the maxi- mum.
