High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic

alternative energy
Hydrogen is one of well-known clean energy source.
Several technologies are already available in the marketplace for the industrial production of hydrogen.
Hydrogen can be produced from a variety of feedstocks.
A variety of process technologi

1) 광촉매란?
일반적으로 촉매(Catalyst)란 어떤 화학반응에서 자신은 변화하지 않고 반응속도를 변화시키거나 반응을 개선시키는 등의 역할을 수행하는 것으로, "광(Photo)+ 촉매(Catalyst)"는 빛을 에너지원으로 이용하여 공기 중의 산소나 물에서 두 종류의 활성산
water and returns to the original substance; water after being used. We can expect that after 2010, the cost of hydrogen as one of the resources should be lower than that of fossil fuel. Fuel cell is the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development
