中文摘要：燃料电池及其应用近些年逐渐成为研究热点，对于系统级的燃料电池运行工况分析及设计，底层的燃料电池本体模型显得至关重要。相比于已有的传统经验模型，重点提出了一种一般性的多物理域燃料电池分析模型，并从电化学域、流体力学域以及热力学动态域对质子交换膜燃料电池进行了精确建模。所提出的框架性建模方法可以适用于不同型号的质子交换膜燃料电池，同时也可以进一步拓展并应用于不同种类的燃料电池。随后以Ballard NEXA 1.2 kW质子交换膜燃料电池为例，对模型在不同工况下进行了仿真，并通过实验测试验证了所提出模型的有效性和准确性。在此基础上，可以展开相应的控制策略及电池本体运行分析，从而提升燃料电池系统的运行性能和工作寿命。
英文摘要：Fuel cell and its applications have gradually drawn research attention in recent years. The fundamental fuel cell model is of great importance to the analysis of the operation condition of a fuel cell system and its design. In comparison to the existing traditional empirical model, a general multi-physical fuel cell analytical model was proposed in this paper, and the accurate modeling of a proton exchange membrane fuel cell(PEMFC) was performed in electroch-emical, fluidic, and thermal dynamic domains. The proposed framed modeling approach can not only be applied to different kinds of PEMFCs, but also be further extended and applied to different kinds of fuel cells. Afterwards, based on the Ballard NEXA 1.2 kW PEMFC, simulations were conducted under varying operation conditions, and the effectiveness and accuracy of the proposed model were verified through experimental tests. On this basis, the corresponding control strategy and the operation of fuel cell itself can be analyzed to enhance the operation performance of the fuel cell system and extend its lifespan.
