초록

청정에너지의 중요성이 부각됨에 따라 수소연료를 활용한 고효율, 무공해 전력 공급원인 연료전지에 대한 관심이 증가 하고 있다. 연료전지는 전기화학 반응에 의한 화학에너지를 직접 전기에너지로 변환시키는 장치로 자동차, 우주항공, 산 업 및 가정용 발전 등에 적용할 수 있는 잠재력이 있다. 최근 재료 및 에너지 변환공정 차원에서 바람직한 200~ 500oC의 온도범위에서 작동하는 중온형 연료전지에 대한 새로운 인식과 이 온도범위에서 사용 가능한 수소이온 전도성 물질의 개발 필요성이 요구되고 있다. 본 논문은 고체 수소이온 전도체의 특성과 기술 현황을 소개하고, perovskite형 고체 무기 산화물을 이용한 중온형 연료전지 응용에 관한 연구에 대하여 고찰하였다

Abstract

Because of an emerging importance of clean energy, fuel cels are atract more atention due to their abilityto produce high efficient power without any harmful emission. Fuel cells are energy conversion device with directlyconvert chemical energy into electrical energy by the chemical reactions, which have potential applications in auto-mobile, spacecraft, stationary, industrial and home appliances. Recently there are gaining demand to develop an inter-mediate temperature fuel cel and available proton conductors at 200~500oC, which promising operating temperaturesproperties and current technology of solid state proton conductors. In addition, development of intermediate temper-ature fuel cell using the perovskite-type solid protonic conductor is also discussed.
