Abstract

The heavy-duty trucking sector shifts towards hydrogen fuel cell vehicles to address CO₂ regulations. Effective temperature management is crucial for optimal performance and longevity of proton exchange membrane fuel cells (PEMFCs). This study focuses on temperature control strategies for cooling systems in dual-stack PEMFC systems used in heavy-duty trucks. Three control strategies based on radiator bypass valve operation are introduced, each aimed at improving dynamic temperature regulation and minimizing parasitic power consumption under interval-steady and World Harmonized Vehicle Cycle (WHVC) conditions.

The results revealed that Strategy No.2, which controls the pump and bypass valve based on fuel cell temperature, deliveries the best temperature control with up to 46 % and 56 % lower Integral of Time-Weighted Absolute Error (ITAE) values under interval-steady and dynamic conditions, respectively, compared to Strategy No.1 (which controls the bypass valve using coolant inlet temperature) and Strategy No.3 (which keeps the bypass valve fully open). However, it also consumes 35 % more parasitic energy compared to the other strategies, highlighting the trade-off between temperature accuracy and energy efficiency. This study provides insights into selecting control strategies that balance these competing factors for improved system performance.

重型卡车双层质子交换膜燃料电池系统冷却系统控制策略分析

重型卡车运输业正在转向氢燃料电池汽车，以应对二氧化碳法规。有效的温度管理对质子交换膜燃料电池（PEMFC）的最佳性能和使用寿命至关重要。本研究的重点是重型卡车使用的双层 PEMFC 系统冷却系统的温度控制策略。研究介绍了三种基于散热器旁通阀操作的控制策略，每种策略都旨在改善动态温度调节，并在区间稳定和世界统一车辆循环（WHVC）条件下最大限度地减少寄生功耗、结果表明，与策略 1（利用冷却剂入口温度控制旁通阀）和策略 3（保持旁通阀全开）相比，基于燃料电池温度控制泵和旁通阀的策略 2 在区间稳定和动态条件下实现了最佳温度控制，时间加权绝对误差积分（ITAE）值分别降低了 46% 和 56%。不过，与其他策略相比，该策略的寄生能耗也增加了 35%，这突出表明了温度精度与能效之间的权衡。这项研究为如何选择控制策略以平衡这些相互竞争的因素，从而提高系统性能提供了启示。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
