Comprehensive Analysis of Platinum-Carbon using Cyclic Voltammetry Characterization in Proton Exchange Membrane Fuel Cell Application for Green Energy Acceleration

PEMFC (Proton Exchange Membrane Fuel Cell) has become one of the solutions for decreasing greenhouse gas emission because its byproduct is water. This technology is related to one of 17 sustainable development goals, that is affordable and clean energy. Nowadays PEMFC is limited in its application because of the high price of platinum as catalyst. One of the strategies to reduce the amount of this platinum is the use of support material to disperse platinum evenly, so even in small amount of platinum but with distribution evenly will give the same result in large amount of platinum without distribution. The material used to be platinum support in PEMFC is carbon. Platinum Chromium from this study, ECSA (Electrochemically active Surface Area) is lower than Pt/C. But with the analysis ordered, we find there is an effect on cycles number of CV (Cyclic Voltammetry). The more cycles number, the larger ECSA will appear. Nitrogen also has a significant role in CV tests. Oxygen is used only for ORR test via LSV (Linear Sweep Voltammetry). The LSV in fuel cell catalysts have important values that can be observed, like number of electrons, symmetry factors, and reaction kinetics. Platinum loading on catalysts is important to note because of their significant effect on electrochemical reaction. Other aspects like reducing agent for hydro chloroplatinic acid, scan rate CV, and electrolyte condition have been well researched for future reference of carbon platinum catalyst fuel cell CV testing.
