摘要

质子交换膜燃料电池的高效运行对工作温度极为敏感，现有冷却流道设计常因强化传热与抑制流动阻力之间的矛盾，难以同时满足高热流密度下的散热需求与电池内部温度的均匀性要求。针对该瓶颈引入集成浴缸型凸起扰流结构的第五代质子交换膜燃料电池（PEMFC）新型冷却通道设计，构建电化学-热-流多物理场的全电池数值模型并进行多物理场耦合分析，系统研究了扰流结构长度比

Abstract

To address the demand for efficient thermal management of proton exchange membrane fuel cells (PEMFCs )

this study investigates the enhancement of thermal management performance using cooling channels equipped with novel bathtub-shaped convex tabulators.A full-cell metaphysics coupled model integrating electrochemistry

heat transfer

and fluid flow is developed to systematically investigate the effects of the tabulators'length ratio (

-1

)

spacing ratio (

-1

)

and width ratio (

-1

) on the heat transfer performance (

)

flow resistance (

) of the cooling channels and the internal temperature field uniformity (

) of the cell. Results indicate that the bathtub-shaped convex turbulators significantly enhance the thermal management performance of the fuel cell by modulating vortex structures

secondary flow intensity

and boundary layer disturbance within the channel.Furthermore

the effects of various structural parameters on thermal management performance exhibit complex nonlinear trends.A comprehensive analysis of heat transfer and flow resistance reveals that the optimal design range is achieved when

-1

is approximately 0.3

-1

is around 0.22

and

-1

is near 0.1 . Under these conditions

f increases by only 1.5% compared to the standard case

while

increases by 21.01%.This study reveals the synergistic mechanism between heat transfer enhancement and flow resistance induced by geometric disturbances

providing data and methodological support for the design of next-generation PEMFC cooling channels that require both high-efficiency thermal management and low flow resistance.
