摘要

与其他类型的燃料电池相比，聚合物电解质膜(PEM)燃料电池由于其更快的瞬态响应和低温运行而非常适合汽车应用。由于汽车应用过程中载荷的快速变化，动态特性的研究是至关重要的。本研究的重点是阐明质子交换膜燃料电池对特定工作参数变化的瞬态响应，即阴极和阳极的电压、压力和化学计量。对单通道PEM燃料电池进行了瞬态数值模拟，以说明工作参数随特定变化时的功率响应。这些参数也进行了优化，目的是在一定时间内匹配汽车驱动循环的功率要求。

Analysis and Optimization of Transient Response of Polymer Electrolyte Fuel Cells

Polymer electrolyte membrane (PEM) fuel cells are well suited for automotive applications compared to other types of fuel cells owing to their faster transient response and low-temperature operation. Due to rapid change in loads during automotive applications, study of dynamic behavior is of paramount importance. This study focuses on elucidating the transient response of a PEM fuel cell for specified changes in operating parameters, namely, voltage, pressure, and stoichiometry at the cathode and the anode. Transient numerical simulations are carried out for a single-channel PEM fuel cell to illustrate the response of power as the operating parameters are subjected to specified changes. These parameters are also optimized with an objective to match the power requirements of an automotive drive cycle over a certain period of time.
