1.Introduction
A fuelcell is a device that converts the chemical energy of a fuel (hydrogen, natural gas, methanol, gasoline, etc.) and an oxidant (air or oxygen) into electricity. A fuelcell operates like a battery. However, a fuelcell does not require recharging, it produces electricity and heat as long as fuel and an oxidizer are supplied.
Fuelcell construction generally consists
the main culprit of air pollution, but people are beginning to understand the diesel car in a different way. The clean diesel engine has a mechanism of compressed air and blast, and it enables the engine to generate the same power as gasoline engine with 30-40% less fuel. It is recognized as an environmentally-friendly car in Europe and is even being referred to as having a ‘Green Engine’. A
vehicles from 2005. Especially, a traditional push strategy(producer-based method) was switched to a pull strategy(customer-based mothod) in the SCM part.

테슬라는 전기차산업 내 경쟁보다는 화석연료를 사용하는 내연기관을 대체할 수 있는 전기차의 보급을 촉진할 수 있는 협력의 장을 마련코자 보유 특허를 개방했다. 이에 따라 전기차산업에서 오픈 소스(open source) 기반의 연구개발이가속화될 전망이며, 자동차업체
1. 차세대 엔진의 현황
위기 뒤에는 기회가 찾아온다고 했던가.
산업혁명의 기원에는 우리가 알지 미처 알지 못한 숨겨진 사실이 있었다. 인류에게 유래 없는 물질적 풍요를 안겨준 산업혁명, 그 산업혁명을 촉진하게 된 계기는 16세기 중엽 이후의 목재 자원의 고갈이었다. 이 연료 위기를 극복하
Li-ion is the best power storage we get
- Good : Light weight, High capacity,
Low self-discharge
- Bad : Safety, Aging, Deep discharging

Integrated gasification combined-cycle (IGCC) systems combine a coal gasification unit with a gas fired combined cycle power generation unit. The first stage is the coal gasification process as mentioned above. The second stage takes the cleaned gas and burns it in a conventional gas turbine to produce electrical energy
