Abstract
PEMFC gradually entered the field of vision of scholars and aroused widespread attention and research, because it has the characteristics of high efficiency, no pollution, and low noise. Traditional PEMFC thermal management system has low efficiency and poor temperature distribution uniformity. This article innovatively proposed a method of using enhanced heat exchange fins for PEMFC thermal management system and established a multi-field coupling simulation model to study the influence of the design parameters of the enhanced heat exchange fins on the temperature of PEMFC, and the optimal fin design scheme is proposed. The results indicated that the fins have an excellent heat transfer enhancement effect, effectively reducing the temperature of each sub-component of PEMFC. Otherwise, different fin angle and fin length have a positive effect on the performance of the thermal management system. Then the design experience of this article can be provided to scholars for reference.
