| Summary: | 碩士 === 逢甲大學 === 材料科學所 === 98 === Proton exchange membrane fuel cell（PEMFC）is nowadays widely studied and discussed in the field. The reason is not only the high electric discharge potency but also the zero pollution that draw attention to. The basic principle for PEMFC is to use the hydrogen to work as the fuel gas and then use the penetration proton exchange membrane to dissociate the hydrogen ions and the electron in order to discharge. The hydrogen ions link up to oxygen at the other end and produce the only by-product - liquid water.
The design of the micro-porous layer（MPL）for PEMFC is not only to attain better cell performance, but also to achieve better water management for the PEMFC system. In this paper, the effects of two different MPL preparation methods, including spraying method and scraping method, on the performance of the PEMFC were researched.
