| 제목 | A Novel design of Composite Support for A Highly Active and Durable PEM Fuel Cell Catalyst |
| 초록 | Polymer electrolyte membrane fuel cell (PEMFC) has been granted extensive attention as a one of attractive electrochemical energy conversion devices. Because, it withholds many benefits such as high energy efficiency, high power density and rapid start up, etc. However, the main problem is the cost of generation still higher than conventional power generators. To overcome this hurdle, researchers are trying to reduce the usage of platinum. In order to use a less Pt catalyst per unit electricity production, more active catalyst with stable support needs to be developed. In this study, a novel composite nanofiber support was prepared by growing carbon nanofibers on the electrospun titania nanofiber using methane as a source. Platinum nanoparticles were deposited on the nanofibrous support by polyol method. Finally, the synthesized catalyst was showed higher activity and improved stability. These properties are characterized by XRD, SEM, TEM, and electrochemical measurements. |
