Abstract
Description
바람직하게는 메탄올 수용액; 에탄올 수용액; 포름산 수용액; 메탄올 수용액과 에탄올 수용액의 혼합물; 에탄올 수용액과 포름산 수용액의 혼합물; 포름산 수용액과 메탄올 수용액의 혼합물; 또는 메탄올 수용액과 에탄올 수용액과 포름산 수용액의 혼합물이다. 이 때 상기 수용액의 농도가 0.01M 내지 17M인 것이 바람직하다. 만약 수용액의 농도가 0.01M 미만이면 전자의 발생량이 적고 만약 17M을 초과하면 애노드 촉매의 일산화 탄소에 의한 피독 현상 및 고분자 전해질을 통과하는 메탄올의 양이 많아져 성능 저하가 일어나 바람직하지 못하다.
