PERBANDINGAN KINERJA MEA PADA PEMFC YANG DIBUAT DENGAN METODE CATALYST COATED SUBSTRATE (CCS) DAN DECAL TRANSFER METHOD (DTM)

---

This study evaluates the performance and durability of Membrane Electrode Assembly (MEA) in Proton Exchange Membrane Fuel Cell (PEMFC) fabricated via Catalyst Coated Substrate (CCS) and Decal Transfer Method (DTM) using Kapton and PTFE substrates. The fabrication technique significantly impacts the catalyst layer structure and electrochemical properties. Characterization through Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), and Linear Sweep Voltammetry (LSV) revealed that DTM PTFE achieved the highest catalyst transfer efficiency of 84,44% and a superior Electrochemical Surface Area (ECSA) of 63 × 10⁻¹⁰ m²/g, outperforming DTM Kapton and CCS. Performance tests showed that DTM PTFE yielded the highest Open Circuit Voltage (OCV), current density, and power density. This superiority is attributed to a more uniform catalyst distribution, whereas the CCS method suffered from catalyst penetration into the gas diffusion layer. A 12-hour durability test on the DTM PTFE MEA confirmed stable operation with minimal voltage degradation. The results conclude that DTM PTFE is the most effective fabrication method for producing high performance and durable MEAs for PEMFC applications.
