Load changes of a polymer electrolyte fuel cell under different operating conditions

A lab scale polymer electrolyte fuel cell (PEFC) with a power of 9 W and an active area of 17.64 cm² was operated with 90% humidity and a stoichiometry factor of two in galvanostatic mode. Load cycles were applied to the PEFC, and the dynamic voltages were monitored. During the experiments shown in jump-run.zip, seven attributes of operating conditions were varied. The experimental setup is specified in detail by Shi [1]. The data files are according to section 5.1 in [1]. The data files in the path jump-run/ contain terms like 0.x-yy, where 0.x is the upper level of the load ramp, starting at 0.2 A cm-2, yy is a numbering of the set of operating conditions, listed in the file 'ramp-up-Experimental setup of DoE methode.pdf'. The parameters A to G are according to Table 5-1 in [1]. The files in the path ramp-up/ contain experiments operated under stepwise increasing electrical load as specified in the file 'jump-dynamic-Experimental setup of dynamic DoE methode.pdf'. The parameters A to G are according to Table 6-1 in [1]. Data with constant operating conditions and different ramp characteristics are published by Froning and et al. [2].

本数据集采用功率为9 W、有效面积为17.64 cm²的实验室级聚合物电解质燃料电池（PEFC），在恒电流模式（galvanostatic mode）下以90%湿度、化学计量比因子为2的条件运行。对该PEFC施加负载循环工况，并实时监测其动态电压。在jump-run.zip压缩包所包含的实验中，共调整了7项运行工况参数。该实验装置的详细说明参见文献[1]中Shi的研究，数据文件的格式符合文献[1]的5.1章节要求。jump-run/路径下的数据文件包含形如0.x-yy的命名格式，其中0.x为负载斜坡的上限值，起始电流密度为0.2 A·cm⁻²；yy为该组运行工况的编号，相关编号列表可参见文件'ramp-up-Experimental setup of DoE methode.pdf'。参数A至G对应文献[1]中的表5-1。ramp-up/路径下的文件包含按逐步递增电负载运行的实验，相关实验设置说明可参见文件'jump-dynamic-Experimental setup of dynamic DoE methode.pdf'，参数A至G对应文献[1]中的表6-1。Froning等[2]已发表了运行工况恒定但斜坡特性存在差异的相关实验数据。
