Role of Nitrogenated Carbon Support in Porous Structure Formation of Pt-CeO_x Based Catalysts

摘要

Fuel cells (FCs) are on the path to become a viable technology of clean and efficient power in the upcoming future. Especially, hydrogen-fueled Proton Exchange Membrane Fuel Cells (PEMFCs) are on the rise of practical applications. Yet, several factors limit the extensive commercialization of these FCs. The main obstacle is the high cost of platinum that is by far the most effective element used for FC catalysts. In addition, the short lifetime of FCs due to the degradation of the catalyst support and the catalyst itself is also a severe constraint. It is essential to overcome these limitations, and thus, the catalyst-support interface is of our primary concern for good FC efficiency.
