초록
하이드라진 직접 액체 연료전지는 이산화탄소를 배출하지 않으며, 높은 에너지 밀도를 가지고, 귀금속 촉매를 사용하지 않고도 높은 촉매 활성을 보이는 장점으로 유망한 연료전지로써 활발히 연구가 진행되어 왔다. 하지만, 고안전성연료전지 운전 성능을 위해서는 전극촉매를 비롯한 핵심소재 개발 및 성능 연구를 토대로 연료의 물질전달 특성을 비롯한 하이드라진 연료전지 내에서 진행되고 있는 작동 프로세스를 충분히 이해할 필요성이 있다. 본 논문에서는 최근의 직접 하이드라진 연료전지 연구결과 중에 가격 경쟁력을 확보한 전극촉매 및 연료 확산, 물 관리, 기체 발생 측면에서 전극 구조 개발 동향을 소개하며 향후 개발 방향에 대해서 고찰하고자 한다.
Direct hydrazine fuel cells (DHFCs) have been considered to be one of the promising fuel cells because hydrazine as a liquid fuel possesses several advantages such as no emission of CO2, relatively high energy density and catalytic activity over platinum group metal (PGM)-free anode catalysts. Judging from plenty of research works, however, regarding key components such as electrocatalysts as well as their physicochemical properties, it becomes quite necessary to understand better the underlying processes in DHFCs for the long term stability. Herein, we highlight recent studies of DHFCs in terms of a systematic approach for developing cost-effective and stable anode catalysts and electrode structures that incorporate mass transport characteristics of hydrazine, water and gas bubbles.
