초록
고분자 전해질 연료전지의 성능은 촉매 지지 물질의 특성에 의존한다. 본 연구에서는 백금 촉매의 지지체로서 CNF(carbon nanofibre)와 CNT(carbon nanotube)를 사용하였다. CNF와 CNT는 기상화학증착법과 메카노케미컬 공정에 의해 처리된 촉매를 이용하여 합성되었다. 백금은 고분자 전해질 연료전지의 적용을 위하여 CNF와 CNT로 지지되었다. 그 결과, 65nm의 직경을 가지는 twisted CNF로 준비된 MEA가 가장 우수한 I-V 특성을 나타내는 것이 확인되었다.
Abstract
The performance of fuel cell electrode depends on the characteristics of the catalyst support material. This paper deals with the use of CNF(carbon nanofibre) and CNT(carbon nanotube) as platinum catalyst support. The CNF and CNT were synthesized with catalyst treated by mechanochemical process and were prepared by chemical vapor deposition (CVD) method. The platinum supported on CNF and CNT for polymer electrolyte membrane fuel cell (PEMFC) application. In result, the best I-V characteristic was verified by the prepared MEA(membrane electrode assembly) from twisted CNF that had a diameter of 65nm.
