1.Introduction
A fuel cellis 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 fuel cell operates like a battery. However, a fuel cell does not require recharging, it produces electricity and heat as long as fuel and an oxidizer are supplied.
Fuel cell construction generally consists
is produced from 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 cellis the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuel cellis increasing, the stage of
Supplying energy for stable is the basis of national survival and economic growth. So thisis very important.
Fuel cellis 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
Pros- Unlike regular fuel cell, 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 fuel cell.
The need for MBFC

Green Car Technologies
Hybrid
The hybrid car has two power sources – an engine and a secondary cell. These sources work respectively or simultaneously according to the driving condition to increase efficiency. Hybrid cars run on battery power at low speeds an
