质子交换膜燃料电池金属泡沫冷却板数值研究

Numerical Study of Metal Foam Cooling Plate for Proton Exchange Membrane Fuel Cell

摘要: 为提升质子交换膜燃料电池冷却板的换热性能，本文基于数值模拟研究了金属泡沫冷却板的换热性能。研究了不同孔密度和孔隙率下的金属泡沫冷却板的换热性能。并且将金属泡沫冷却板与直流冷却板和蛇形冷却板在不同热通量、流速和冷却液温度下进行了比较。结果表明，金属泡沫能控制整体温度，但是压降会有一定程度的上升；热通量的增加会使温度进一步增加，建议通过增加冷却液流速和降低冷却液温度来综合控制温度。

Abstract: To improve the heat transfer performance of cooling plates for proton exchange membrane fuel cells, this paper numerically investigates the heat transfer performance of metal foam cooling plates. The study examines the heat transfer performance of metal foam cooling plates with different pore densities and porosities. Furthermore, the metal foam cooling plate is compared with straight-channel and serpentine cooling plates under various heat fluxes, flow velocities, and coolant temperatures. The results show that the metal foam can control the overall temperature, but the pressure drop increases to a certain extent. An increase in heat flux further raises the temperature. It is recommended to comprehensively control the temperature by increasing the coolant flow velocity and reducing the coolant temperature.
