A fuel cell is a device that transfers the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent [1]. Fuel cells can produce electricity continuously until these inputs are supplied. The first fuel cells were invented in 1838. Since then‚ fuel cells have been used in many other applications. Fuel cells are used for primary and backup power for industrial‚ commercial and residential buildings and in inaccessible

ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

Fuel injection in diesel engines [edit] Mechanical and electronic injection Older engines make use of a mechanical fuel pump and valve assembly which is driven by the engine crankshaft‚ usually via the timing belt or chain. These engines use simple injectors which are basically very precise spring-loaded valves which will open and close at a specific fuel pressure. The pump assembly consists of a pump which pressurizes the fuel‚ and a disc-shaped valve which rotates at half crankshaft speed
