⑴ 연료전지발전
연료전지발전(FuelCell 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.
Fuelcell 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.
Fuelcells are direct energy conversion into electricity. So High electric conversion eff
fuel. Fuelcell is the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuelcell is increasing, the stage of the development is still slight. To develop fuelcell technique as the core industry, we have to construct effective infrastructures from extraction to supply. So, in this project, our team has sea

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
Pros- Unlike regular fuelcell, MBFC can make energy in very mild condition.- MBFC can produce energy by consume variety organics.
Cons- MBFC need electrochemical mediator this mediator generally not degradable and very poisonous. so mediator can make 2nd pollution.- Output is low and unstable compared to general fuelcell.

The potential difference above the equilibrium value required to produce a current which depends on the activation energy of the redox event.
