고분자전해질 연료전지 특징? | 고분자전해질 연료전지 (Polymer Electrolyte Membrane Fuel Cell, PEMFC) 는 높은 효율을 가지고 환경오염물질을 배출하지 않기 때문에 친환경적인 에너지원으로 주목받고 있다. 하지만 높은 비용과 내구성 문제로 인해 상용화가 저해되고 있다. | |
연료전지 양극에서 일어나는 반응? | 하지만 높은 비용과 내구성 문제로 인해 상용화가 저해되고 있다. 연료전지의 연료극 (anode) 과 공기극 (cathode) 에서는 각각 수소 산화 반응과 산소 환원 반응이 일어나는데 느린 산소 환원 반응 속도를 증가시켜야 연료전지 전체의 성능을 증가시킬 수 있다.1-3) | |
