Fuel Cell, , Fuel cell is an electrochemical cell which converts chemical energy, contained in readily available fuel oxidant system into electrical energy., , Fuel cell is that the fuel & oxidant are stored outside the cell. Fuel and, Oxidant are supplied continuously and separately to the electrodes at which they, undergo redox reactions., , Eg: H,-O, fuel cell, Methanol -O, fuel cell, , Fuel + Oxidant > Oxidation Products + electricity
