초록

연료전지는 가까운 미래를 위한 핵심 청정 신에너지원 중의 하나로 기대된다. 그러나 고분자 연료전지에서 공기극은 느린 산소환원반응과 많은 백금 사용 때문에 상업화에 어려움을 겪고 있으며, 이것을 해결하는 것이 최근 당면 과제이다. 또한 연료극은 일산화탄소의 피독 현상과 전극의 안정성이 문제시 되고 있다. 본 총설에서는 고분자 연료전지를 위한 연료극, 공기극 전기화학 촉매의 이론적 접근을 통해 촉매를 설계하는 최근 연구 내용을 소개하려 한다. 촉매 설계는 합금 전기화학 촉매를 통해 접근 했으며, 이는 electronic, geometric, lateral effects를 손쉽게 조절할 수 있게 한다. 이것은 계산되어진 d-band center의 함수에 의존하며, 촉매의 활성과 큰 관계를 가짐을 발견하였다. 본고에서 지향하는 촉매의 최종 방향은 이론적 접근을 통해서 촉매의 사용량을 줄이면서 효율적으로 사용하는 것이다.

Abstract

Fuel cells are expected to be one of the major clean new energy sources in the near future. However, the slow kinetics of electrocatalytic hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR), and the high loading of Pt for the anode and cathode material are the urgent issues to be addressed since they determine the efficiency and the cost of this energy source. In this review paper, a new approach was developed for designing electrocatalysts for the HOR and ORR in fuel cells. It was found that the electronic properties of Pt could be fine-tuned by the electronic and geometric effects introduced by the substrate alloy metal and the lateral effects of the neighboring metal atoms. The role of substrate was found reflected in a volcano plot for the HOR and ORR as a function of their calculated d-band centers. This paper demonstrated a viable way to designing the electrocatalysts which could successfully alleviate two issue facing the commercializing of the fuel cell - the cost of electrocatalysts and their efficiency.
