Abstract:As we know, the new generation is only relying on electricity and their storage devices like batteries, cell etc. so this paper is reviewing fuel cell and their types that’s help us in the future.A fuel cell is an electrochemical cell that convert chemical energy intoelectricity energy through chemical reaction like redox and oxidation reaction. Fuel cells are different from most of the batteries in requiring a continuous source of fuel and oxygen to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from metals and their ions or oxidesthat are commonly already present in the battery, except in flowbatteries. Fuel cells continually produce energy if oxygen is provide to fuel cell.
