Alkaline법의 장점은? | 전기를 이용하여 물로부터 부산물인 산소와 고순도의 수소를 대량 생산할 수 있는 장점이 있다. 다양한 수전해 방법 중 상업화 된 Alkaline법은 비귀금속을 사용하며, 장시간 사용에 유리하고 가격이 저렴한 장점을 가지고 있지만 낮은 전류밀도를 보여주며 alkaline용액에서 사용하기 때문에 부식성으로 인해 내식성이 큰 전극이 필요한 단점이 있다[9,10]. Proton exchange membrane (PEM) 수전해 방법은 고체고분자 전해질막을 사용하여 양극에서 음극으로 수소이온이 이동하는 이온교환방법으로 셀 구조가 간단하고 alkaline법과 비교하여 높은 전류밀도로 높은 효율을 보여주지만, 높은 설치비용과 낮은 용량을 가지며 값비싼 귀금속 촉매를 사용하고 수명이 짧은 단점이 있다[11,12]. | |
수소를 에너지원으로 사용하는 것의 장점은? | 그 중 하나가 수소를 에너지원으로 사용하는 것이다[3-8]. 수소의 가장 큰 장점은 쉽게 수소에서 전기에너지로 다시 수소로 전환 가능하다는 점으로 수소를 사용하는 과정에서 발생되는 부산물은 단지물 이고, 또 물을 이용해서 수소를 재생산할 수 있다. 수소는 천연가스 개질, 태양열, 바이오매스, 전기분해 등을 이용하여 생산할 수 있다. | |
수소는 무엇을 통해 생산가능한가? | 수소의 가장 큰 장점은 쉽게 수소에서 전기에너지로 다시 수소로 전환 가능하다는 점으로 수소를 사용하는 과정에서 발생되는 부산물은 단지물 이고, 또 물을 이용해서 수소를 재생산할 수 있다. 수소는 천연가스 개질, 태양열, 바이오매스, 전기분해 등을 이용하여 생산할 수 있다. 현재는 천연가스 개질을 통해 전체 수소의 95% 이상을 생산하며, 이 때 수소는 화석연료로부터 얻어지기 때문에 완전한 의미의 신재생에너지원이라 하기는 어렵다. |
