| Popis: | This paper summarizes the performance of PEMFC catalyst layer. The main materials used as catalyst in PEMFC are presented as well as the typical structure of MEA. Functions of catalyst during the operation of PEMFC are discussed in detail. Catalyst plays a key role in accelerating the rate of electrochemical reaction, especially that of reduction with oxygen in cathode. But its high cost and low tolerance for has resulted in a severe fact that essentially all the longevity of PEMFC which adopts precious metal-platinum or platinum alloys as catalysts is relatively short. A sputter deposited method is presented to enhance the efficiency of catalyst in PEMFC, while whether this method would bring about a striking effect or not remains worth further researches. |
