PEMBUATAN KATALIS Ni-Fe/C DENGAN KOMPOSISI BERVARIASI MENGGUNAKAN METODE BALL-MILLING DAN APLIKASINYA PADA PRODUKSI HIDROGEN BERBASIS PEMWE

The increasing global energy demand and environmental impacts of fossil fuels have driven the development of clean and sustainable energy sources. Hydrogen is a promising alternative due to its environmentally friendly nature and significant potential in future energy systems. Hydrogen production through water electrolysis using Proton Exchange Membrane Water Electrolysis (PEMWE) is efficient and produces high-purity hydrogen. The performance of PEMWE systems is strongly influenced by the Membrane Electrode Assembly (MEA), particularly the catalyst layer. This study aims to determine the effect of variations in Ni and Fe composition on Ni-Fe/C catalysts synthesized through impregnation and ball milling on material characteristics, electrochemical performance, hydrogen production, and MEA durability. The catalysts were synthesized from NiCl2·6H2O and FeCl2·4H2O precursors supported on carbon with varying Ni:Fe ratios and characterized using XRF, CV, LSV, and EIS. The electrodes were assembled into MEAs and tested in a PEMWE system under varying current and voltage conditions. A catalyst Ni:Fe ratio of 1:1 showed the best performance, achieving an ECSA of 1,352 m2/g, conductivity of 0,113 S/cm, and electrical charge of 0,00002 C. Increasing current enhanced hydrogen production, while voltage influenced catalyst efficiency. The highest hydrogen output occurred at Ni:Fe ratios of 1:1 and 1:2. Durability tests revealed decreased production due to degradation of the Nafion 117 membrane and catalyst layer. Keywords : Ni-Fe/C catalyst, PEMWE, MEA, Hydrogen, Ball-Milling
