Search to find a producer of fuel ethanol reached a promising stage. The basis of this research is the fuel cell technology. A fuel cell works as an electrochemical cell by combining hydrogen and oxygen without combustion to generate electricity. A series of load cells or requires drainage after prolonged use. But a fuel cell will produce electricity if the fuel remains forever.

The mechanics of a fuel cell sandwiched between two electrodes of an electrolyte. When oxygen is passed over one electrode and hydrogen is passed over the second, it generates heat, water and electricity. Waste water expelled
