Development of high performance PEECs stronglr reqiures visualization of thermo-fluid phenomena inside the cells, such as the temperature and water content distributions in MEA. This research project aims at developing a novel PEFC cell that enables visualization of the tempamperature field of the MBA and the water content distribution in the electrolyte polymer membrane. Part of the cell separator(s) is replaced with optical window(s) that is (are) transparent to certain wavelength of visual and infrared lights for visual observation of channel flow phenomena, thermography temperature measurement and spectroscopic infrared absorption measurement of membrane water content The results clearly exhibit the unique conjugate phenomena of the thermo-fluid phenomena with electrochemical reaction. There is a distinct temperature distribution along the channel, and the distribution can be changed by changing the various operation parameters. The water content also has a distribution along the channel. The experimental results are combined with numerical results in order to provide high performance operation of PEFCs where the exhaust water and gas temperature can be maintained at high level and the temperature distribution does not have high peak These results have given a big impact to the industry where no visualization technique has been provided before.

高性能 PEEC 的开发强烈需要细胞内热流体现象的可视化，例如 MEA 中的温度和水含量分布。该研究项目旨在开发一种新型 PEFC 电池，使 MBA 的温度场和电解质聚合物膜中的水含量分布可视化。将部分细胞隔板替换为对一定波长的可见光和红外光透明的光学窗口，用于目视观察通道流动现象、热成像温度测量和膜水含量的光谱红外吸收测量结果清楚地展示了热流体现象与电化学反应的独特共轭现象。沿通道存在明显的温度分布，并且可以通过改变各种操作参数来改变该分布。水含量也沿河道分布。实验结果与数值结果相结合，以提供PEFC的高性能运行，其中排出的水和气体温度可以保持在较高水平，并且温度分布没有高峰。这些结果对行业产生了很大的影响，其中之前没有提供可视化技术。
