초록

현재 수소에너지는 화석연료의 고갈과 환경문제를 동시에 해결할 수 있는 가능성 있는 자원으로 그 중요성은 점점 커지고 있으며 지금까지 비 화석연료로부터 수소를 생산하는 방법 중에서 관심을 받는 기술은 물 전기분해이다. 물 전기분해는 전기에너지를 이용하여 무한정한 원료인 물로부터 고순도의 수소와 산소를 생산할 수 있는 친환경적인 방법이다. 본 총설에서는 물 전기화학반응의 기본원리와 종류, 최근 국내외 기술 개발현황과 발전가능성에 대해서 기술하고자 한다.

Hydrogen energy becomes more attractive in that it can resolve the exhaustion of fossil fuels and their environmental problems. Until now, water electrolysis has been a interesting technique to produce hydrogen from non-fossil fuels. In principle, water electrolysis is an environmentally friendly technique to split water into hydrogen and oxygen, so that it can be utilized without any limitation of resources. Herein, we introduce basic understanding and three types of water electrolysis. Furthermore, the research trend and patent analysis will be followed along with an outlook.
