*1.3.2. Catalyst*

"Platinum" is a common noble metallic that acts as a catalyst in the acidic fuel cell environment. The platinum catalyst in the form of tiny particles is deposited on the large surface area of the carbon cloth for a better reaction. The platinum catalyzes the conversion of hydrogen molecule of the fuel into electrons and protons at the anode side. Moreover, at the cathode side, it helps to split oxygen molecule into two atoms and then combines with the electrons and protons from hydrogen to produce water. Platinum catalyst is extremely sensitive to CO poisoning from the fuel gas derived from hydrocarbon fuel[7].
