목차 The background of Topic selection About Fuel cell Auxiliary power unit Performance of Hybrid power source Conclusion : Hybrid System Q & A 본문 features1. fuel cell is a kind of generator that provides electricity, batteries are like warehouses that store electricity. features2. The maximum output energy from the battery = 50% forms of energy+50% heat =>The energy efficiency is 50%. features3. large energy density. (store a lot of energy per weight) Recently, as the amount of storage for capacitors rose, higher level of electricity application became possible to realize. (ex) Uninterruptible(UPS), Hybrid automobile supercapacitors have a lot in common with batteries, but we can say that they are the newest form of battery. You can charge it in a very short period of time and repeat a number of charge and discharge periods. The energy efficiency is much higher than a battery. 키워드 재료공학, Hybrid power source, 영문
