| Research Abstract |
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.
