1. Fuel Cell의 구조 및 작동원리
⑴ 연료전지발전
연료전지발전(Fuel Cell Power Generation)은 천연가스 등의 연료를 개질(改質)해서 얻어진 수소를 연료로 해서, 이 수소와 산소가 화학반응하면서 발생하는 전기에너지를 이용하는 새로운 발전 시스템이다.
연료전지는 화학에너지를 전기에너지로 변환한
Supplying energy for stable is the basis of national survival and economic growth. So this is very important.
Fuel cell is worthy of notice other alternative energy.
It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.
Fuel cells are direct energy conversion into electricity. So High electric conversion eff
Li-ion is the best power storage we get
- Good : Light weight, High capacity,
Low self-discharge
- Bad : Safety, Aging, Deep discharging
