114學年材料所-第十二週 專題研討課程 演講公告 (114年11月27日)
2025.11.24
題目:
質子交換膜燃料電池電極與雙極板研發
Electrode and bipolar plate development for PEM fuel cells
演講者 : 曾重仁(Chung-Jen Tseng)
現職 : 國立中央大學 能源工程研究所 特聘教授
時間: 114年 11月 27日(四) 3:20~4:00 pm
地點: 鋼構區(3F)共同教室A1302演講廳
演講摘要:
In this talk, we will summarize what we have been working on improving the performance of proton-exchange membrane fuel cells (PEMFC). Primary focuses are catalyst layer enhancement through laser processes and bipolar plate development in the past few years. Pt nanoparticles are deposited on to gas diffusion layer (GDL) by using pulsed laser deposition (PLD) in argon atmosphere. The resulting catalyst layer is optimized and characterized for the application in PEM fuel cell. Furthermore, a picosecond laser was used to fabricate grooves on the GDL surface to increase the effective surface area for Pt deposition, thereby reducing local Pt film thickness. Pt mass specific power density of over 8 kW/g at 1 atm can be achieved.
