Abstract
Abstrak The sol-gel casting technique has been used for the fabrication of membrane elektode assemblies (MEA) as a means for better disribution of metal catalys, such as Pt, residin g on the membrane surface, this in itself will make the catalyst used to more eefficient. The precusor contained Tetra Ethoxy Ortho Silicate (TEOS) as the silica sourse and Phospotungsticacid (PWA) as the proton conductive material. The electrolyte membrane, Nafion 112 waas impregmetes with the prcursor solution containing PWA and TEOS before its coated with the catalyst ink to produce the elektrodes. The elektrodes were fused with the gas diffusion layers (GDL) hot press at 120◦C and presure 30 atm for 4 minutes to produce the membrane elektrode assembly (MEA). Catalyst loading in to the membran surface varies from 0,38 until 0.475 mg/cm2. Characterization of the membrane electrode assemblies (MEA) conducted by fuel cell test system. Comparison sol-gel MES to the commercial MEA at the same operation condition but lower catalyst loading in anode/cathode (0,4/1) mg/cm2 on commercial MEA and (0,43/0,43) mg/cm2for sol-gel MEA show a better performance. The result of the experiment show sol-gel MEA product more high curret and voltage along test time during 12 hours, and show stability of current and voltage durung 30 hours test time at ambient temperature. So that could to be conclude that sol-gel process is applicable for MEA and have advantages improve performance of PEMFC
