UJI KINERJA DAN DAYA TAHAN MEMBRANE ELECTRODE ASSEMBLY (MEA) DENGAN KATALIS Pt/C PADA PEMFC SEL GANDA

---

The use of fossil fuels such as coal, petroleum, and natural gas, which have a negative impact on the environment, has encouraged the development of clean and sustainable renewable energy sources, one of which is hydrogen, which can be used as fuel in fuel cells to generate electrical energy. One type of fuel cell that has been widely developed is the Proton Exchange Membrane Fuel Cell (PEMFC), with efficiency and operational stability that are highly dependent on the performance of the Membrane Electrode Assembly (MEA) as the core component where electrochemical reactions take place. MEA performance is influenced by the distribution of gas and water flow evenly on the GDL and catalyst layer. This study aims to determine the results of MEA characterization with Pt/C catalyst in a dual�cell PEMFC using Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), and Linear Sweep Voltammetry (LSV) methods, to determine the effect of hydrogen flow rate and humidifier temperature on MEA performance, and to determine MEA durability based on voltage drop during operation time. MEA performance testing was conducted with hydrogen flow rate variations of 100, 200, 300, 400, and 500 mL/min and humidifier temperature variations of room temperature, 40°C, 60°C, 80°C, and 100°C, as well as durability testing for 720 minutes under optimal conditions. The results showed that MEA characterized using the CV, EIS, and LSV methods obtained an ECSA value of 3×10-7 m²/g, an electrical conductivity value of 1,37×10-9 S/cm, and an electrical charge value of 3,71×10-6 C. The optimum performance of the MEA with a Pt/C catalyst in a dual�cell PEMFC was obtained at a hydrogen flow rate of 200 mL/min and a humidifier temperature of room temperature, producing a current density of 3,009 mA/cm² and a power density of 1,497 mW/cm². The durability test of the MEA with a Pt/C catalyst in the dual-cell PEMFC showed a voltage drop of 0,0643 V after 720 minutes of operation. Keywords : Hydrogen, Fuel Cell, PEMFC, MEA, Pt/C Catalyst
